>>> a.sort() >>> >>> a [1, 2, 3, 4, 5] sorted()是python的内置函数,并不是可变对象(列表、字典)的特有方法,sorted()函数需要一个参数(参数可以是列表、字典、元组、字符串),无论传递什么参数,都将返回一个以列表为容器的返回值,如果是字典将返回键的列表。 1 2 3 4 5 6 7 8 9 >>> ...

reversed()is a built-in function in Python. In this method, we neither modify the original list nor create a new copy of the list. Instead, we will get a reverse iterator which we can use to cycle through all the elements in the list and get them in reverse order, as shown below....

Python中 reverse()是列表的内置方法,无参数,无返回值,reverse()会改变列表(原地反转),因此无需返回值。字典、元组、字符串不具有reverse()方法,如果调用将会返回一个异常. >>> help(list.reverse) Help on method_descriptor: reve...
