Python list 之 append 和 extend

append和extend都仅只可以接收一个参数，append 任意，甚至是tuple，extend 只能是一个列表

>>> myList = [1,2.0,'a']>>> myList[1, 2.0, 'a']>>> myList.append('APP')>>> myList[1, 2.0, 'a', 'APP']>>> myList.extend([123,'abc'])>>> myList[1, 2.0, 'a', 'APP', 123, 'abc']>>> myList.append(1,2)Traceback (most recent call last):  File "<pyshell#69>", line 1, in <module>    myList.append(1,2)TypeError: append() takes exactly one argument (2 given)>>> myList.extend([1],[2])Traceback (most recent call last):  File "<pyshell#70>", line 1, in <module>    myList.extend([1],[2])TypeError: extend() takes exactly one argument (2 given)
