The first obvious reason for this is, in wildcard imports, the names with a leading underscore don't get imported. This may lead to errors during runtime. Had we used from ... import a, b, c syntax, the above NameError wouldn't have occurred. >>> from module import some_weird_...
No.1 一切皆对象 众所周知,Java中强调“一切皆对象”,但是Python中的面向对象比Java更加彻底,因为Python中的类(class)也是对象,函数(function)也是对象,而且Python的代码和模块也都是对象。 Python中函数和类可以赋值给一个变量 Python中函数和类可以
