//What does it mean in python?

In python // means taking integer division and returning the integer part of the quotient (rounded down)

#!/usr/bin/python# -*- coding: UTF-8 -*- a = 10 b = 5 c = a//b print "c 的值为：", c

Output:

c 的值为： 2

Note:

In Python2.x, dividing an integer by an integer can only result in an integer. If you want to get the decimal part, just change one of the numbers to a floating point number.

>>> 1/2 0 >>> 1.0/2 0.5 >>> 1/float(2) 0.5
