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.
