How to get pydoc command working in Windows?

Use python -m pydoc os instead of pydoc directly, no need to add to path variable.

the -m tells python that pydoc is a pre-built module in python and NOT a script (.py file) sitting in the current working folder.

See https://docs.python.org/3/using/cmdline.html for details

PS adding C:\python27\Lib\pydoc.py to the Windows path in the system environment variables does not work. Even after logging out and back in it does not work.

The PATH environment variable is a list of directories to search for a given executable. So you should be adding C:\python27\Lib to your PATH (not including the filename).

As for the pydoc.bat file you've created, one place to put it would be the C:\python27\Scripts directory which is usually added to your PATH by the python installation (since that folder contains miscellaneous scripts that you might like available at the command line).

I have found in windows 10 powershell...

Remember to access pydoc in windows, it's python -m pydoc. If you want to access info on "file", add the word "file"after. Like this "python -m pydoc file" (*w/o the quotes).

What you type after python -m pydoc, will tell it what info you want brought upand/or looking for. i.e. python -m pydoc raw_input, python -m pydoc string, python -m pydoc file.

Remmeber python -m pydoc must be in front of what you are looking for.
