what should i do to run python commands.
Modify your setup. Open "Programs and Features" from the control
panel. Right-click the entry for Python 3.5 (not "Python Launcher")
and select Uninstall/Change. In the dialog, click on "Modify". Click
"Next" and select "Add Python to environment variables". Click
"Install". When it's done, open a new command prompt and enter
"python".
Or he could just use "py", which is the python launcher you just
mentioned, and works fine. If he has other versions of python installed
he may need "py -3".
That works on my machine and I wondered why.
It seems to do it by simply putting a special executable (py.exe) into
C:\windows, which is the first (or second) place it will look when
someone types the name of a program.
But a bit of a cheat I think, and probably not good practice (suppose
all your hundreds of apps put dedicated launchers into C:\windows which
is supposed to be for OS stuff).
(And if you're going to do that, you can also just put a one-line script
in there to launch any program.)
