Answer Source

The % (modulo) operator yields the remainder from the division of the first argument by the second. The numeric arguments are first converted to a common type. A zero right argument raises the ZeroDivisionError exception. The arguments may be floating point numbers, e.g., 3.14%0.7 equals 0.34 (since 3.14 equals 4*0.7 + 0.34.) The modulo operator always yields a result with the same sign as its second operand (or zero); the absolute value of the result is strictly smaller than the absolute value of the second operand [2].

Taken from http://docs.python.org/reference/expressions.html

**Example 1:**
`6%2`

evaluates to `0`

because there's no remainder if 6 is divided by 2 ( 3 times ).

**Example 2**: `7%2`

evaluates to `1`

because there's a remainder of `1`

when 7 is divided by 2 ( 3 times ).

So to summarise that, it returns the remainder of a division operation, or `0`

if there is no remainder. So `6%2`

means find the remainder of 6 divided by 2.
