1. What does the Python list reverse() method do?The reverse() method reverses the order of elements in a list in place.2. Does the Python list reverse() method modify the original list?Yes, the reverse() method modifies the original list by reversing the order of its elements.3. Does...
If you don't mind overwriting the original and don't want to use slicing (as mentioned in comments), you can call reverse() method on the list. >>> num_list = [1, 2, 3, 4, 5]>>>num_list.reverse()>>>num_list [5, 4, 3, 2, 1] If you want to loop over the reversed ...

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: reverse(...) L.reverse() -- reverse *IN PLACE* >>> l=[1,2,3,4,5]...
类对象的类型是type,即,类对象是type的一个实例对象。自定义函数对象的类型是function,内置函数对象的类型是builtin_function_or_method(如type(dir)是这个,type(dir())是list)。可以用运算符==判断某个对象的类型是否是指定的类型。不是基本数据类型需导入模块types使用其中定义的变量。
