一边循环一边计算的机制——生成器（generator）创建一个生成器法一：将[]改为()即可l = [x*x for x in range(3)]g = (x*x for x in range(3))print(l)print(next(g))# 结果[0,1,4]<generator object <genexpr> at x000001C819194C10>若要打印g，则需要使用next()print(next(g))print(next(g))p

Python 学习笔记——连续赋值问题关于`赋值顺序`关于赋值顺序a = b = 'hello'其顺序等同于a = 'hello'b = 'hello'再比如list.next = list = ListNode(1)#相当于list.next = ListNode(1)list = ListNode(1)如果想要达到list.next = ListNode(1)list = list.next# 就可以写成上面的形式list.next = list = ListNode
