I am taking a codeacademy beginners course in Python. What does the character "%" mean in this expression - 45 % 12? I am using Python 2.7.5. i have looked at various references, and cannot find it.

It's a modulus operator. – Anderson Green Jan 23 '14 at 23:09

I have some slight doubt that you have looked at "various references".... – nye17 Jan 23 '14 at 23:11

second hit with google, so -1: "% operator python" resulted in "Modulus - Divides left hand operand by right hand operand and returns remainder". I hardly believe you could not find a proper explanation, this operator exists in so many languages. Sorry for your first question. – angabriel Jan 23 '14 at 23:12

It's the modulus operator - 45 divided by 12 = 3 and 9/12. In short, it would return 9.
It's a neat way of looping up to a certain count
eg the following will run on alternate rows...
for i in range[0,100]
if i % 2 == 0:
#Even row
else:
#Odd row

The % (read "mod" or "modulo") means divide by and return the remainder:
x = 8%3
The above expression says "divide 8 by 3 and compute the remainder. Assign this remainder to x"
