Hi, welcome to Python.
This list is about how to install programs written in Python - as a
matter of respect for the time of the other folk here, we can't really
discuss the issue you've had.
But - I can hopefully point you in a useful direction:
You might find https://wiki.python.org/moin/BeginnersGuide/Programmers
useful if you already know how to program, or
https://wiki.python.org/moin/BeginnersGuide/NonProgrammers if you do
not already know how to program.
At a guess, the specific issue you are facing is a
bytestring/textstring difference - you can find more out about those
through the links above.
HTH,
Rob
