The difference between python command line operation in win and Linux systems

Today, I am completing a small python exercise. The main content of the exercise is to read a help module and save it to a local file.

I know that pydoc is used to read the module, but under the windows system, after calling the os module, the result is always empty.

Core statement:

helpfile = os.popen('pydoc %s' %module).read()

This statement can run normally under Linux and the result is normal.

It was later discovered that under Windows, the modification is:

helpfile = os.popen('python -m pydoc %s' %module).read()

Command line operation requires the use of Windows command line statements.

The above is the entire content of this article, I hope it will be helpful to everyone learning Python
