*Anaconda 3 (with the add to path option)
Afterwards C:\Python27 and C:\Python27\Lib were added to the path. C:\Python27\python.exe was copied to C:\Python27\python2.exe and C:\ProgramData\Anaconda3\python.exe was copied to python3.exe. Users can therefore run eitherany of the following:
python -- runs python 3.7 in C:\ProgramData\Anaconda3
python3 -- runs python 3.7 in C:\ProgramData\Anaconda3
python3 python2 -- runs python 2.7 in C:\Python27 py -3 -- runs python 3.7 in C:\ProgramData\Anaconda3 py -2 -- runs python 2.7 in C:\Python27
