How to recursively work with multiple nested lists

Create a multi-tiered list (that is, a list of stored lists) and output list items

The following figure:

You can see that the output is only output out of the list

Of course, you can iterate through each subkey multiple times: As shown in the following figure

Note: Isinstance (object, ClassInfo) is a built-in function of Python to determine the type of object

This is a three-tier loop, and it's too cumbersome to recycle the For loop output for many times.

For this situation, a function needs to be established, and the recursive loop output child

As shown in the following illustration:

Simply create a function print_lol (), and if the built-in function isinstance () determines that the subkey is a list, call the function print_lol () itself

The movies is then used as the parameter of the function print_lol to invoke the function output list subkey

For this nested list, you can also output one of the items by using an array subscript

Such as:

>>> print (movies[5][1][1])  
sex  
>>>
