Talk about the terminal directly execute py file do not need python command

Then give the script file permission to run,

Method (1) chmod +x./*.py

Method (2) chmod 755./*.py (777 doesn't matter)

If this command is not adjusted, an permission denied error will occur

The terminal executes directly.

If a comment similar to the following is given at the beginning of the script content:

#! /usr/bin/env python (or #! / usr/bin/python)

That can be run directly from the terminal:

./*.py

If you don't have this comment

Execute in the terminal:

python ./*.py

(note: some versions of linux run on python even if the above comment says python in front of python as a command.

Otherwise, the file./*.py is not a command./*.py not found error will appear. The command can't be found, of course.)

If it's a script with a graphical interface

After chmod, just double-click to execute
