This article mainly introduces "how the Linux system runs python". In the daily operation, I believe that many people have doubts about how the Linux system runs python. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "how the Linux system runs python". Next, please follow the editor to study!

1. Run python using python's IDEL

If your Linux installs python,Ctrl+Alt+T and opens Terminal, enter the command: python, it will appear >, and then you can enter python script into it to start running.

Use exit () to exit the python environment

It is similar to MATLAB in this environment.

(1) check the python version: enter under python idle:

Import sys

Sys.version

Or it will be displayed when entering idle.

Or enter the instruction under Linux Terminal: python-version, or python-V

2. After writing the test.py script file, execute the script python test.py in the terminal

It means to run the script test.py using the python interpreter

3. After writing the test.py script, use chmod + x test.py to add execution permission to the script, and you can run it.

. / test.py

Note that sometimes things go wrong.

Usually we need to add #! to the first line of the .py file. / usr/bin/env python

This sentence means that the interpreter address of the script file is specified as python. Without this sentence, the system will automatically use the shell interpreter by default.

Of course, you can also use the python installation path directly. If python is installed in the / usr/bin directory, then use #! / usr/bin/python. It is recommended that you use #! / usr/bin/env python.

At this point, the study on "how the Linux system runs python" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
