Python Help

Trying to learn python, just for fun(not for a class) and didn't get far. Why does this keep asking saying can't assign to operator? It is supposed to keep asking for input until it reaches 100.

while number_total < 100:
    number = input("Give number please")
    number_hold = number_total
    number + number_hold = number_total

What's the easiest imageboard script for newfags?

  number + number_hold = number_total
should be
  number_total = number + number_hold

assignment is right to left

thank you. bought a python book so i can continue to learn
