Python 允许这些不被实际使用的对象存在，然而聪明的 IDE 应该会有所提示（我用的是Pycharm），比如告诉你：Statement seems to have no effect 。但是“...”这个常量似乎受到了特殊对待，我的 IDE 上没有作提示。很多人已经习惯上把它当成 pass 那样的空操作来用了（在最早引入它的邮件组讨论中，就是举了这...

Note: All Python functions have a return value, either explicit or implicit. If you don’t provide an explicit return statement when defining a function, then Python will automatically make the function return None. Even though all expressions are statements, not all statements are expressions. Fo...

True is False == False is equivalent to (True is False) and (False == False) and since the first part of the statement (True is False) evaluates to False, the overall expression evaluates to False. 1 > 0 < 1 is equivalent to (1 > 0) and (0 < 1) which evaluates to True. Th...
