I am just starting to write my first Python scripts and everything was fine, until yesterday when I tried to run a Python script in cmd. Usually, I type: cd Desktop, and than file.py. It always worked, but suddenly when I type file.py, it opens up the script in Notepad++ and it doesn't run the program in cmd. I hope that someone can help..

  • You don't give us enough details, check the PATH environment variable and be sure that the path to python.exe is present.

  • you could always do python file.py, well in case python.exe is in system path

  • This happens because of Windows file association. Something happened that caused .py files to be associated with Notepad.exe.

Guess in your windows env, .py file already being assign to open with notepad++

Right click any .py files, click properties, change the open with to your python executable, eg. C:\python27\python.exe

OR

Explicitly specify to run it with python in cmd

cd Desktop
python file.py
