Python Math

Guess what computers do? They compute. And they’re very, very, very good at it. It’s no wonder, then, that programming languages are literally made to do math. There’s not much to show here, I’ll be brief:

numberOfCats = 4 + 3 # numberOfCats would be 7

numberOfDogs = 8 / 2 # numberOfDogs would be 4

numberOfHamsters = 3^2 # numberOfHamsters would be 9

For the record, the thing with the hash mark is a comment. These are ignored by the code. When you enter a hash (#), you are telling the compiler - the thing which reads and runs your code - to ignore anything that comes after the hash mark on that line. Simple concept, sure, but worth covering.
