下表列出了所有Python语言支持的成员运算符。

在Python中使用成员运算符的示例

 例如:

试试下面的例子就明白了所有的Python编程语言提供会员运算符:

#!/usr/bin/python

a = 10
b = 20
list = [1, 2, 3, 4, 5 ];

if ( a in list ):
  print "Line 1 - a is available in the given list"
else:
  print "Line 1 - a is not available in the given list"

if ( b not in list ):
  print "Line 2 - b is not available in the given list"
else:
  print "Line 2 - b is available in the given list"

a = 2
if ( a in list ):
  print "Line 3 - a is available in the given list"
else:
  print "Line 3 - a is not available in the given list"

当执行上面的程序它会产生以下结果:

Line 1 - a is not available in the given list
Line 2 - b is not available in the given list
Line 3 - a is available in the given list
