Because computers only know binary information (only 0 and 1), binary information is too difficult to understand compared with what we usually say, so in order to communicate with computers well, various computer programming languages have appeared, including Java.

Java can be recognized by computers because Java compilers and Java virtual machines translate information written by people into binary information that can be recognized by machines, so that we can communicate with computers well. This specification is called Java language.

Java is an object-oriented language. The so-called object-oriented means that in Java programming, all operations are operated through objects, so that when we are programming, we can treat a function as a class and set our own properties for such things.

Because there are many advanced computer languages (C/C, JAVA, Python, C#, etc. ), different languages focus on different fields, and Java focuses on enterprise application development in the Internet industry.

Like the shopping platforms we often use and the management platforms of some companies, most of them are developed in Java. Moreover, the Android mobile phone system and APP we are using now are also developed in Java language.

Python is an object-oriented explanatory computer programming language with rich and powerful libraries, so it is often called glue language, which can easily connect various modules made in other languages (especially C/C), and is one of the key development languages used by many enterprises at home and abroad. The founder of python is GuidovanRossum, and the development of python is influenced by Mola-3 language. Python is easy to read, extensible and concise, and is taught to students by some famous universities as the main programming language. People in the industry generally call python a high-level dynamic programming language, which can be used for large-scale software development.

Python has a wide range of applications, such as back-end development, full-stack development, reptile development, artificial intelligence, financial quantitative analysis, big data, Internet of Things and so on. Python applications are everywhere. Google, YouTube, Douban and other large well-known websites all use Python to complete the core code, which shows that the development prospect of Python is immeasurable.
