下表列出了所有Python語言支持的成員運算符。

 例如：

試試下面的例子就明白了所有的Python編程語言提供會員運算符：

#!/usr/bin/pythona = 10b = 20list = [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 = 2if ( 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"

當執行上面的程序它會產生以下結果：

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