Python not working in command prompt?

Question

I type python into the command line, but the command prompt says that python is not recognized as an internal or external command, operable program, or batch fi

Answer 1

It finally worked!!!

I needed to do things to get it to work

1. Add C:\Python27\ to the end of the PATH system variable
2. Add C:\Python27\ to the end of the PYTHONPATH system variable

I had to add these to both for it to work.

If I added any subdirectories, it did not work for some reason.

Thank you all for your responses.
