Read the documentation here https://docs.python.org/3/ and then run up 
your favourite editor and start typing.  When and if you hit problems 
come back with a snippet of code that shows the problem, what you 
expected to happen, what actually happened, and the full traceback if 
there is one.  Please use cut and paste to ensure that you get the data 
correct.

My fellow Pythonistas, ask not what our language can do for you, ask
what you can do for our language.
