Python 3 installation was working fine until yesterday. Then this happened today. Output from command prompt (Windows 10) when I type Python:

Fatal Python er         


        

Answer 1

This may be due to an invalid value of PYTHONPATH set in your system. Unset the value of this environment variable using the following command unset PYTHONPATH This should now fix the problem. If the problem still persists, then re-install Python. Your issue should be solved now.
