下表列出了所有Python语言支持的成员运算符。
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
