Error in code NameError: name ' ' is not defined

As others have said, you created numb as an int and are then trying to define variables inside of it.
There are at least two simple solutions:
1) Define a variable for each case.

#Instead of 
numb.x = 0
#use 
numb_x = 0

2) Use a dictionary

numb = {}
numb['x'] = 0
numb['y'] = 0
