It seamlessly works on distinct platforms like Mac, Linux, Windows, Mac, Raspberry Pi, and more. It executes on an interpreter system. It means, as of it, code can be run as instant as we write it. Briefly, prototyping can be highly swift. It has simple and easy to understand syntax like the English language. We can use it functionally or procedurally. It has a syntax that endows developers to write programs quickly in fewer lines as opposed to other developers. What is the functioning of Python?

It can be connected to database systems to read and amend files To manage big data and also to perform complicated mathematics It is used on a server to establish website applications For rapid prototyping For production-ready software development It is used equally with software to develop workflows What are the top 10 reasons to learn Python Language In 2020? Although, abundant reasons are associated with using Python language in 2020, let’s highlight the best below:

Python’s popularity & high salary Python is simple & easy to learn Python is portable & extensible Python is used in Data Science Python is used in scripting & automation Python used with Big Data Python supports Testing Computer Graphics in Python Python used in Artificial Intelligence Python in Web Development 1. Python’s popularity & high salary The primary reason associated with the popularity of Python is, it is a great and easy way to learn to code. It has a feature of quickly writing complicated tasks. Many significant applications only support Python language.

The popularity of the Python language in 2020 will be very high. As per the survey of the TIOBE Index for February 2020, this programming language ranks in the number 3 slot. It honored with the title of fast-rising programing language that comes under the top 50.

Python ranks 3_TIOBE Index for February 2020 In addition to it, Popularity of Programming Language Index (PYPL) ranked Python as the most popular language based on search engine searches as opposed to different programming languages. The fact, as compared to the last five years, Python has been grown to 17.6%.

Reasons for being a popular language-Python
Python is a versatile language when needed for website development. Python is considered instrumental in AI and data science Python excessively and uninterruptedly used in the Internet of Things Python highly recommended when learning to code Moreover, the demand for Python developers is very high. As per Stack Overflow’s Developer Survey, this programming language ranked 2nd in the world as of its versatile nature.

Moreover, Industry leaders like

YouTube Amazon Google Facebook IBM NASA Netflix make the use of this language. Even more prominent companies are adopting this language that makes the demand for Python developers very high.

According to Slash Data, more than 8.2 million developers are using this language, while 7.6 million developers are using Java in the world. Moreover, the number of Python developers are increasing day by day.

The average salary of a:

Software developer with Python skills is around $76,746 and more for an entry-level developer and very high for a senior developer (around $90K). Web Developer with Python skills is around $59,108 and $77000 for a senior developer. Data Scientist with Python skills is around $97,663, and for veteran and experienced specialists, it touches to $140000.

Why does Python language preferable than other data science tools? Robust and simple to use Python is a language that is quickly learned and use even by the beginners or any student by just learning the basics of it. It has very minimized constraints and debugging codes. In other languages like C, C++, Java, etc. the time required to code implementation is less, which takes much to the time of developers to work on their algorithm.

Scalable Python proves to be a highly scalable programming language. It solves problems that can’t be solved by other languages like Java. Many businesses have been used in this language to establish applications and tools instantly.

Options of Libraries When users use Python, they experience a big database of libraries, machine learning, and artificial intelligence. The most popular libraries it is using are Seaborn, Scikit Learn, Pytorch, Pytorch, and Matplotlib.

Extensive Visualization and Graphics options Python developers find many options for visualization and graphics. Even they can use their charts, graphical layouts, web-ready plots, etc.

Python’s scripting & automation Being an open-source scripting language, we can easily automate anything on Python. A python learner as a beginner can quickly learn its basics and gradually able to write its scripts to automate data or stuff available around.

To automate stuff in Python, only the following scripts needed to write: The code must be written in scripts only to get an execution. To check the error should during the run time. The machine is used to read and interpret the code. Once the developer checked the code, it can further run or used several times without any interruption. Thus, with automation, users can automate many tasks or stuff in a program.

Python used with Big Data To complete the big data job accurately, Python is considered the best data science tool. When there is a need to integrate web application and data analysis with the production database, then big data and Python is the best solution.

Let’s shed light on reasons when Python is the best choice for big data:

Why to learn java in 2020
1. Java Can Do Everything The Java programming language has not been the leader for more than a decade now by chance. Indeed, Java really allows you to do everything in the world of computing. With Java, you can build desktop applications using the Swing API or JavaFX. JavaFX is a more modern solution for developing graphical interfaces. Since Java 11, JavaFX has been developed by the OpenJFX community, which does a great job. The Jakarta EE specification, formerly known as Java EE, allows the development of complete web applications (Internet or Intranet). This specification provides a complete stack that allows developers to architect their applications in the best possible way. All this explains why Jakarta EE is so popular in companies. Android’s hegemony over the world of mobile telephony also allows Java to be the ideal language for developing mobile applications. In the world of cloud computing, leading service providers such as Amazon, Google, and Microsoft all support Java programming language for application development. Of course, Java remains present in the embedded system with the Java Card solution. The Internet of Things (IoT) is set to grow exponentially in the future with the deployment of 5G around the world. Here again, Java is there because it is widely used in this promising field. Finally, if it is not necessarily the preferred solution in data science or in the world of machine learning, Java also has its followers in these domains. In short, Java makes it possible to do everything right. This is not always the most appropriate solution, but a Java developer has a very wide range of possibilities.

2. Java Is Easy To Learn Learning to program is never easy. If this is your case, you will need to have a strong will to achieve it. Nevertheless, as you learn, you will realize that all your efforts are really worth it. Java is easy to learn because it is very popular and a large number of free resources are available for training. Many tutorials are available but also a large number of forums where you can ask questions when you get stuck in your learning. Then, from a technical point of view, Java is ideal because it is an imperative language but also object-oriented. These two paradigms are the most common in companies but also the easiest to master for beginners. Finally, if you are an experienced developer with other object-oriented languages, you will quickly become comfortable with Java, which offers a rich and intuitive API with very high quality documentation.

3. Java Is Widely Used In Companies In the world of computer programming, several methodologies are used to measure the popularity of a programming language. Among the existing methodologies, the TIOBE index is frequently used as a reference. The TIOBE index still ranks Java as the most popular language. The popularity of the Java language is found in companies where it is widely dominant. In the universities where it is de facto very often taught to students. Finally, novice developers are becoming more and more interested in it as they embark on the development of Android applications in their spare time. The fact that Java is so widespread makes it an excellent choice because once you master it, you will be able to apply for many Java developer positions in companies or try to get freelance Java development assignments. Investing time in learning Java is therefore a guarantee that you will benefit from it in your career as a developer.

4. Java Has A Strong Community The Java community is one of the most important in the world of computer programming. This is quite logical since Java is an ultra-popular and open-source language. The strong Java community is a great asset since you will always find a library already written that meets your needs. This abundance of open source projects written in Java will give you a wide choice of code libraries when you face issues. As I explained earlier, this strong community is also a great asset when you encounter problems developing programs in Java. Indeed, someone will probably have already encountered your problem and you will save valuable time by consulting the solution they have used. Finally, this strong community allows Java developers to have at their disposal a whole bunch of excellent tools for free, such as IDEs (Eclipse, IntelliJ IDEA,…), dependency managers (Maven, Gradle, Ant,…) or application servers (Tomcat, TomEE, Wild Fly, Jetty, …).

5. Java Is Free In 2018, Oracle announced in a somewhat confusing way that the JDK would now be charged for professional uses in production. Obviously, the confusion has led some to argue that Java has become a paid service! Contrary to what some may have believed or said, Java is always free. In reality, Oracle now distributes two builds of the JDK: Oracle JDK Oracle OpenJDK Oracle JDK is a free development and testing environment but you have to pay to use it in production. It comes with long-term support from Oracle. On the other hand, Oracle OpenJDK is free for any environment. Thus, Java remains free as long as you use Oracle OpenJDK. In addition, there are other implementations of the JDK that you can choose to use, which ensures that Java is free in the long term. For example, you can use the JDK builds proposed by the Adopt OpenJDK community. More recently, Amazon has just made its own JDK builds available under the name Amazon Corretto with completely free long-term support. The fact that Java is free and especially that it will remain so in the future is a strong point in his favor. When you choose a programming language to learn, I advise you to look at this point carefully.

6. Java Is The Cobol Of The 21st Century This title is a little provocative, I must admit. I think he caught your attention right away. Indeed, you must wonder why I advise you to learn Java in 2020 when I call it the Cobol of the 21st century. The fact that Java is the Cobol of the 21st century is something positive for me. The Cobol language was created in 1959. While he has just celebrated his 60th birthday, Cobol is still very popular in banks and insurance companies. More than 60 years after its creation, Cobol is still present in companies and allows developers to earn comfortable salaries to maintain all the applications created over the past decades. Java was created in 1995 and is extremely popular in companies. I draw a parallel with the Cobol to show you that Java will still be a widely used solution in companies in 2050 and surely even in 2100. In fact, the need for developers to maintain the very large number of Java applications deployed will always be enormous. By choosing Java in 2020, a developer ensures a full career in the IT industry.

7. Java Is Also An Execution Platform With the JVM Java is an ultra popular programming language. However, Java is much more than that. Indeed, Java is also a complete execution platform with its virtual machine, the famous JVM (Java Virtual Machine). Kotlin, Scala or Groovy are the most popular programming languages among the many running on the JVM. Once you have learned the Java programming language, a new world will open up for you: the world of programming languages running on the JVM. Kotlin, Scala or Groovy are the popular ones, but there are others. Each of these languages has been launched to fill some of the gaps in Java in specific areas. When it was created, Scala aimed to make functional programming accessible on the JVM for example. Faced with the significant popularity of Scala, Java 8 finally saw the JDK acquire a number of functionalities from the world of functional programming. These open source languages running on the JVM can therefore be considered as fields of experimentation that Java architects then use to improve the language. Kotlin also has a bright future ahead of it since Google chose it to be the second official programming language for the Android operating system.

8. Java Is Very Fast By learning the Java programming language in 2020, you will enter the world of JVM. This world is very fast. Don’t listen to those who still claim that Java is slow compared to compiled languages like C and C++. The so-called slowness of Java is a myth that has lived on. This myth is based on some truth since the first versions of Java were indeed slower than compiled languages such as C or C++. In order to keep its promise “Write Once, Run anywhere”, the Java platform had to make some concessions and its virtual machine, the famous JVM, added a layer of software. In fact, performance could suffer in some specific cases. In addition to this problem of the additional software layer, some implementations of the JVM were really slow in the beginning. Nevertheless, this myth has lived on and C or C++ aficionados must face the facts: the JVM is now fast. I would even say that it is ultrafast! In addition, hardware has progressed so much since the early years of Java that the addition of an additional software layer, such as JVM, has no real impact on performance for the vast majority of enterprise applications. Finally, the JVM Just-In-Time (JIT) compiler is a pure marvel that greatly improves the performance of Java applications. The level of performance achieved by the JVM is such today that it serves as an execution platform for a large number of Kotlin, Groovy and Scala languages. So, we are no longer only talking about the Java language but also about the Java ecosystem. Today, Java is a scalable platform that is perfectly adapted to tomorrow’s IT challenges.

9. Java Is Evolving Fast During the end of Sun Microsystems’ reign as head of the JDK, Java’s evolutions tended to slow down significantly. Oracle’s early years at the helm of Java were no better. Thus, it took 11 years between Java 6 and Java 9! Starting with Java 9, Oracle has decided to adopt a new lifecycle for Java releases. This new lifecycle guarantees a major new version of Java every 6 months with new features experienced faster thanks to the following both statuses : preview and incubator. Since the release of Java 9 in September 2017, Oracle has kept up this pace, which allows Java to evolve faster and respond more quickly to developers’ expectations. Thus, Java 14 is already scheduled for March 2020.

10. Java Has A Rich Standard API The JDK offered with the Java programming language provides developers with an extremely rich standard API. Thus, you will be able to create graphical interfaces for the desktop with Swing or AWT, do multithreaded programming, manage inputs/outputs operations, perform network operations, access databases or even manipulate time without the need for external code libraries. The richness of the standard Java API is a major asset. With Java, you can touch all the fundamentals of computer programming directly without having to manage a whole bunch of dependencies. Of course, you will need to integrate external code libraries when developing more complex applications afterward. Nevertheless, for your learning of the Java language, the standard API will be more than enough. Conclusion As we enter a new decade in 2020, Java is more than ever a programming language to learn. Whether as a first language or to broaden your programming skills, Java will bring you a lot and will be a significant asset to your career. Of course, Java is not always the most appropriate language for each domain in the computer industry. Nevertheless, Java has the advantage of being versatile while benefiting from an execution platform, the famous JVM, extremely powerful which will give you the possibility to create high-performance and scalable programs. And, if you want to learn Java in 2020, here are some of the most recommended courses
