整理Python中的赋值运算符

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
