This article will explain in detail about the types and characteristics of the Python interpreter, the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

What is the python interpreter?

English: Interpreter, also known as literal translator, is a computer program that can directly translate and run a high-level programming language line by line. The interpreter does not translate the whole program at once, just like a "middleman". Every time the program is run, it has to be converted to another language before running, so the program of the interpreter runs slowly. Every time it translates one line of program narration, it runs immediately, and then translates the next line, and then runs again, and so on and on.

The brain of the computer is CPU, which is called CPU in Chinese. It cannot directly process the Python code that we have edited. CPU can only deal directly with machine instruction languages, which are made up of 0 and 1 digits. So we need an intermediate translator to translate the Python language into a machine instruction language that the computer CPU can understand so that the computer can do things according to the requirements of our Python program.

Python is an interpreter language, and if the code wants to run, it must be executed through the interpreter. Python has a variety of interpreters, which are developed based on different languages. Each interpreter has different characteristics, but it can run Python code normally. Here are five commonly used Python interpreters:

CPython

The official interpreter: CPython. This interpreter is developed in C language, so it is called CPython. Running python from the command line starts the CPython interpreter. CPython is the most widely used Python interpreter.

IPythonIPython is an interactive interpreter based on CPython, that is, IPython is only enhanced in the way it interacts, but the function of executing Python code is exactly the same as CPython. CPython uses > > as the prompt, while IPython uses In [serial number]: as the prompt.

PyPyPyPy is another Python interpreter whose goal is execution speed. PyPy uses JIT technology to dynamically compile Python code (note that it is not interpreted), so it can significantly improve the execution speed of Python code.

Most Python code can be run under PyPy, but there are some differences between PyPy and CPython, which results in different results for the same Python code executed under the two interpreters. If your code is to be executed under PyPy, you need to understand the differences between PyPy and CPython.

Jython

Jython is a Python interpreter running on the Java platform, which can directly compile Python code into Java bytecode for execution.

IronPythonIronPython is similar to Jython, except that IronPython is a Python interpreter running on Microsoft's .net platform that compiles Python code directly into .net bytecode. There are many interpreters for Python, but the most widely used one is CPython. If you want to interact with the Java or .net platform, the best way is not to use Jython or IronPython, but to interact through network calls to ensure the independence of each program.

On the Python interpreter types and characteristics of what is shared here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
