我是靠谱客的博主单纯黑裤，最近开发中收集的这篇文章主要介绍整理Python中的赋值运算符，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

下表列出了所有Python语言支持的赋值运算符。假设变量a持有10和变量b持有20，则：

例如：

试试下面的例子就明白了所有在Python编程语言可供选择的赋值运算符：

#!/usr/bin/python

a = 21
b = 10
c = 0

c = a + b
print "Line 1 - Value of c is ", c

c += a
print "Line 2 - Value of c is ", c 

c *= a
print "Line 3 - Value of c is ", c 

c /= a 
print "Line 4 - Value of c is ", c 

c = 2
c %= a
print "Line 5 - Value of c is ", c

c **= a
print "Line 6 - Value of c is ", c

c //= a
print "Line 7 - Value of c is ", c

当执行上面的程序，它会产生以下结果：

Line 1 - Value of c is 31
Line 2 - Value of c is 52
Line 3 - Value of c is 1092
Line 4 - Value of c is 52
Line 5 - Value of c is 2
Line 6 - Value of c is 2097152
Line 7 - Value of c is 99864
