What does "//" mean in python?

"//" in python means rounding and dividing, and returns the integer part of the quotient (rounded down). There are other operators in python: " " (addition), "-" (subtraction), "*" (multiplication), "%" (modulo), "/" (division), "**" (power) .

python//Indicates integer division and returns the integer part of the quotient (rounded down)

There are other operators in python:

Add - Add two objects a b Output result 30

- Subtract - Get a negative number or subtract one number from another number a - b Output result -10

* Multiply - Multiply two numbers or return a string repeated several times a * b Output result 200

/ Division - Divide x by y b / a Output result 2

% Modulo - Return the remainder of division b % a Output result 0

** Power - Return x raised to the y power a**b is 20 of 10 Power, the output result is 100000000000000000000

// Divide by integer - return the integer part of the quotient (rounded down)

Example:

#!/usr/bin/python
# -*- coding: UTF-8 -*-
 
a = 21
b = 10
c = 0
 
c = a + b
print "1 - c 的值为：", c
 
c = a - b
print "2 - c 的值为：", c 
 
c = a * b
print "3 - c 的值为：", c 
 
c = a / b
print "4 - c 的值为：", c 
 
c = a % b
print "5 - c 的值为：", c
 
# 修改变量 a 、b 、c
a = 2
b = 3
c = a**b 
print "6 - c 的值为：", c
 
a = 10
b = 5
c = a//b 
print "7 - c 的值为：", c

Result:

1 - c 的值为： 31
2 - c 的值为： 11
3 - c 的值为： 210
4 - c 的值为： 2
5 - c 的值为： 1
6 - c 的值为： 8
7 - c 的值为： 2
