Hi! Im Sghet, im starting to program in Python 3. Im learning with the "Python crash course" of Eric Matthes. One of the project is to code a game similar to Space invaders. I had the game running without a problem until I implemented a button to make the game start, Now im having this error.
The game run perfect until i added the button
Ps: Is there a place in the forum to make introductions? I dont seem to find it!
Error:

Im Sorry if this is a alot of code. I didnt know if providing only the part that has the "ship.blitme()" would be enough to help me!
