Hi i am new in Python.

I've tried running this on cmd / powershell : python app.py

but it doesn't do anything.

Since i am using python 3 i also tried: python3 app.py but it came out as

'python3' is not recognized as an internal or external command, operable program or batch file.

  • the error has nothing to do with flask. did you even try to run simple python shell after installation? – Ali Faizan Jan 03 '20 at 04:35

  1. Add Python3 to your PATH.

  2. run python3 -V

  3. If it prints out the version.

    Test python3 app.py. Make sure you have installed required pip packages.

    else

    something wrong with you python3 env

  4. If nothing happens when test python3 app.py

    check you app.py
