Setting .py file to notepad as default mistakenly

Question

I mistakenly set .py file to notepad as default mistakenly and it opens .py as txt file, but I don't want to open .py files with any program. I searched stackoverflow but solutions did not work for me. How can I solve it?

Answer 1

Probably, this one: How do you remove a default program association for file types in Windows 7?

Answer 2

Not a python-related question.

• Open Command Prompt in Administrator Mode.
• Type assoc .py at the prompt. (If the association is set with notepad, the same will be shown.)
• To not associate .py with any program (careful!) type assoc .py=. This sets the association to a non-existent value - simply, deletes it.
