This wikiHow teaches you how to open Python files using the built-in Command Prompt program on Windows computers. 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 installing and did not add the “python” command to the “Path” variable list, proceed to add Python to the “Path” variable list to be able to start run the Python file through Command Prompt.
Steps
Find Python file path
- If you already know the directory path of the Python file to open, you can open the file on Command Prompt right away.
- You can copy the location by highlighting the information (click and drag your mouse over the “Location” value) and then press Ctrl + C .
Launch Python file
. Click the Windows icon in the lower left corner of the screen. The Start menu will pop up.
Command Prompt appears at the top of the Start menu. Command Prompt will open.
- For example, to open a Python file located in the “Files” folder on the Desktop, you need to enter cd desktop/Files here.
- If you copied the file path then type cd with a space and then press Ctrl + V to paste the path.
- For example, if the Python file is named “script” then you need to enter python script.py here.
- If the Python file has more than one space in the name, we enclose the name with the file extension in quotes (e.g. python "my script.py" ).
- If the error
'python' is not recognized as an internal or external command
appears after pressing Enter , you need to add Python to the PATH list and then try again.
