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
