I am trying to run a python script from the windows command prompt, but I receive the following error message:
\"python: can\'t open file \'pacman.py\': [Errno 2] No
PYTHONPATH is used by the python interpreter. It is not the same as Windows' PATH environment variable. You can't use it as a search path for passing files to the interpreter on the command line.
So, you need to specify a valid path to the file. Either by using he same command as you've been trying with the difference being your current directory is the same as the location of pacman.py, or by specifying the full path to the file.
