pip not working in Python Installation in Windows 10

instead of typing in “python”. try using “py”.
for ex:

py -m pip install    packagename
py -m pip --install  packagename
py -m pip --upgrade  packagename
py -m pip upgrade    packagename

note: this should be done in the command prompt “cmd” and not in python idle. also FYI pip is installed with python 3.6 automatically.
