Class and inheritance in Python

# my example to show a shell for class's for a game in Python
# I'm sure there is a better way, but this will kinda show you how to make the inheritance, and class thing
# work together. You can switch the modules around to any class, as long as the class is defined before you #use them. 

##  Meggamuffins is my name!  Eating mushrooms is NOT my game!

#When you run this in terminal, it should show you how the order is written backwards,

# but the computer processes it bottom up.  Same as the other shell, but in all classes.

pygame vector image bounce with Vector class

##### mostly this code is re-written, but if I had to look for it, maybe you did too
##  if you cut and paste (which you should type yourself to learn)  just the
## import  math, and vector class , and the stuff that's
## edited out at the bottom, you can see what the vector class does
## I looked forever for a code to make the object bounce, or follow.
## nobody really says, "you have to have a vector class, or module to do it"
## apparently you do.   If not, let me know in comments, I'd love to learn how
