Installing pip packages on Windows 10 tablet

[jazmad]

python version is 3.7.0
pip --version does not return any result and I just get a new command line (as when I go to install a new package). I've copied the text from Command Prompt below to illustrate this.

C:\Users\vaqui\AppData\Local\Programs\Python\Python37-32>python --version
