Removed argparse.py

I use Ubuntu 18.04. By mistake, I changed argparse.py file in usr/lib/python3.6. I couldn't fix it and I thought to remove it, so I could reinstall. Now I can't reinstall, whenever I try "pip install argparse" I get an error like this:

Defaulting to user installation because normal site-packages is not writeable

Could you please help me to fix this?

argparse is (since Python 3.2) part of the standard library. Just get the file from the official github (I'm assuming cpython, adapt the version as necessary by selecting the correct branch, the link is for python 3.8) and put it back where the one you deleted was

argparse is part of the standard library, not a third-party module. The standard library is not managed via pip (that is both its blessing and its bane).

So you have to fix or reinstall python itself.
