Hop Game

[confusedman]

Hello i am new to python and i am getting increasingly worried. I have a deadline on tuesday and i have to make a game in python. I have tried and tried but i am useless at python.

Therefore i have decided to finish off a piece of code that my lecturer gave to me. However it is making my head hurt i am so confused. Can anybody help me display a character and get it to move?

        pygame.display.flip()

I will be very grateful for any help.
Thankyou.

Fix your indention. Return from __init__ does not make sense.
