I am using Python 3.5.2 version on Windows 7 and tried using
python3 app.py. I am getting this error message:
'python3' is not recognized as an internal or external command, operable program or batch file.
Is there any specific cause about why the
python3 command is not working?
I also verified that the PATH is added to environment variables.
There is no python3.exe file, that is why it fails.
py is just a launcher for python.exe. If you have more than one python versions installed on your machine (2.x, 3.x) you can specify what version of python to launch by
py -2 or py -3
