Python is a high-level, general-purpose programming language, known for its concise, easy-to-read syntax, is widely used in web crawlers, data analysis, machine learning, artificial intelligence and many other fields. Specifically install python development environment method, the following operation:

Go to the official Python website and selectDownloadstitle bar, you can see that there are corresponding Windows and macOS options.

Here we select the Windows option to the right ofPython 3.12.4 If you are interested in downloading the latest version of the program, click on the download page. You can directly download the latest version of the currentPython parser installer.

There are two major versions of Python parsers, Python 2 and Python 3, but the dominant version is Python 3.

For general-purpose versions and program compatibility reasons, we don't usually use the latest version of python, but we recommend Python 3.7, Python 3.8, or python 3.9.

Recommended for 3.7, 3.8, 3.9 (newer versions are less stable)

For example, we chose the 64-bit .exe installation file for Python 3.9.12 under Python 3.9 version. Click on it to download it directly.

After selecting the address of the installation file, clickInstallcarry out the installation

After successful installation, clickCloseJust close the window.

Here's congratulations to the reader for having successfully installed the Python parser. Next we need to configure the computer'senvironment variable. The purpose is that when we run Python code, the system will first look for the Python parser you downloaded (here installed 3.9.12 parser), after finding the Python parser, the general call Python parser to recognize, compile and run your Python code.

So configuring your computer's environment variables here is the equivalent of configuring the address that your computer is going to call, and you need to tell your computer where to find the Python parser.

Searched in the search box environment variable Four keywords to choose from Editing system environment variables Options.

Click high level under the environment variable options (as in computer software settings)

decide upon a candidate system variable lower PathThen click below compiler Options.

Once selected, click upward shift Make it move to the first position and click OK

 Congratulations to our readers who have successfully configured their environment variables. Next we need to do a little test, the purpose of which is to determine whether our computer can properly call the Python parser.

In endpoint window by typing "Python-version." command, and then press the keyboard Enter key.

Python-version The intent of the command is to show the version of the Python parser that is currently on your computer. If the Python parser is installed and the system environment variables are configured, the terminal will run the command and display the current Python version number. If you get a runtime error, you may not have configured the environment variables properly.

If the version number pops up, congratulations on having the Python parser installed and working.
