This wikiHow teaches you how to open Python files using the Command Prompt program built into your Windows computer. In most cases, you will open the file without any problems as long as Python is available on the machine. If your computer uses an old version of Python, or you customized it when installed and did not add the "python" command to your list of "Path" variables, add Python to your list of "Path" variables so you can start. Run Python files through Command Prompt.
