How do I remove the list within the big list?

The question is:

Use .remove() and/or del to remove the string, boolean, and list members of the_list.

lists.py 
the_list = ["a", 2, 3, 1, False, [1, 2, 3]]

# Your code goes below here
the_list.insert(0, the_list.pop(3))
del the_list[1]
del the_list[4]

Disclaimer: I don't have much Python experience, but I am familiar with the basics via experience with other languages.

You can use the list.remove() to remove items from a list using their values. There are probably multiple ways to solve this problem.

the_list.remove("a")
the_list.remove(False)
the_list.remove([1, 2, 3])

Edit - Okay, I redid the challenge using your method. Remember that when you delete items from the list, the indexes of the other items may change!!

del the_list[1] # [1, "a", 2, 3, False, [1, 2, 3]]
del the_list[3] # [1, 2, 3, False, [1, 2, 3]]
del the_list[3] # [1, 2, 3, [1, 2, 3]]
