Which one should I learn first, python or java?

We know that both Java and Python are very popular programming languages ​​today, so choosing which language to learn becomes a difficult problem for students who have just started learning programming. Because I am a programmer myself, if I give you subjective advice, it will obviously be biased. I will suggest that you learn Java first and then learn Python, but if you ask a Python programmer, you may will get the opposite answer.

#We can conclude from the analysis of famous communities around the world that Java has always been a more popular language, whether it is Zhihu, CSDN or the more professional StackOverFlow In other communities, there are always more discussions and issues related to Java than other languages.

When I first came into contact with Python, I thought it was just a scripting language, but later I discovered that this was my misunderstanding. After all, Python is also a scripting language. It is a powerful object-oriented programming language, and it is very active in various communities. There are still many people who like this programming language. If we want to choose a language that is attractive, simple and powerful, and has strong community support, obviously these two languages ​​​​meet the conditions. We still have to continue to struggle. So let's do some other comparisons.

The first point is the amount of code. It takes 10 lines of code to read a file through I/O in Java, but only two lines of code are enough in Python. This is an advantage of Python, because novice programmers definitely want to write less code.

The second point is about static variables and non-static variables. My point is that for novices, you need a language with strong type constraints and a rigorous compiler to prevent you from making mistakes. In Java, you will not write code with confusing variable types, but in Python you will not You need to have some knowledge in mind, so I like Java very much for this.

The third point is execution speed. This is the lifeblood of enterprise-level applications, and Java is obviously faster than Python.

The fourth point is that you need to compile the code before running Java, but Python can be run directly without compilation. Python commands can be directly interpreted in the Python console, which is more important for novices. of simplicity.

So after a little comparison, we found that each of the two languages ​​has its own advantages. We will not continue to compare. Which language you choose is indeed worthy of your careful consideration, especially in combination with your major and What you plan to do in the future. But don’t let this problem bother you for too long. After all, time is precious. Come on, only when you are on the right path can you make a real choice in your heart.

Finally, as a Java programmer, I speak from my personal perspective: You will not regret learning Java and treating it as a programming language for your career. Of course, you can also use your spare time Take the time to learn Python and write some practical gadgets. Having said so much, if you are still struggling, wouldn't it be over if you just take them all? This is the state that a technician should have. Is not it?
