__enter__()和__exit__()对应with语句(即with所求值的对象中必须有__enter__()方法和__exit__()方法) 当我们对类的对象使用这些函数或者运算符时python解释器就会自动调用类中对应的魔法方法。 Iterable可迭代对象 iterable官方API An object capable of returning its members one at a time. Examples of ...
先看官方定义(docs.python.org/3.8/glo): A function which returns a generator iterator. It looks like a normal function except that it contains yield expressions for producing a series of values usable in a for-loop or that can be retrieved one at a time with the next() function. ...
