Specify the full location to python.exe One way to fix the error would be to launch Python from the Command Prompt by passing in the full path to the executable file each time you wanted to run Python. In other words, instead of typing Python you would type something like C:\Users\me\path\to\python.exe .
Try "py" instead of "python" from command line:
C:\Users\Cpsa>py

You need to add that folder to your Windows Path:
https://docs.python.org/2/using/windows.html Taken from this question.
Firstly, be sure where your python directory. It is normally in C:\Python27. If yours is different then change it from the below command.
If after you install it python still isn’t recognized, then in PowerShell enter this:
[Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27", "User")
Close PowerShell and then start it again to make sure Python now runs. If it doesn’t, restart may be required.
Type py -v instead of python -v in command prompt
If you want to see python version then you should use py -V instead of python -V
C:\Users\ghasan>py -V
