### What does the percentage sign mean in Python

In the tutorial there is an example for finding prime numbers:

``````>>> for n in range(2, 10):
...     for x in range(2, n):
...         if n % x == 0:
...             print(n, 'equals', x, '*', n//x)
...             break
...     else:
...         # loop fell through without finding a factor
...         print(n, 'is a prime number')
...
``````

I understand that the double `==` is a test for equality, but I don't understand the `if n % x` part. Like I can verbally walk through each part and say what the statement does for the example. But I don't understand how the percentage sign falls in.

What does `if n % x` actually say?
