it's the modulo operator (if you don't remember, the modulo is the 
remaining of the integer division, ie 5 % 2 = 1)

One of the most commun use is to test wether a number is odd or even:

any_even_number % 2 == 0
any_odd_number % 2 == 1


Note that the % operator is also used for string formating, ie:
"%d modulo %d = %d" % (5, 2, 1)
=> "5 modulo 2 = 1"
