Python Collection - Last Challenge Can't remove list item from list

for this challenge I wrote the following code: the_list = ["a", 2, 3, 1, False, [1, 2, 3]]

move_item = the_list.pop(3) the_list.insert(0, move_item)

removed = []

for item in the_list: if type(item) is bool or type(item) is str or type(item) is list: location = the_list.index(item) print (location) del the_list[location]

print(the_list)

The output I got was:

1 3 [1, 2, 3, [1, 2, 3]]

Process finished with exit code 0

For some reason the if statement doesn't catch the list item and puts its index in the location var. What am I doing wrong?

Thanks,

:point_right: Skipped items can result from modifying the iterable inside a loop.

To make sure you check every item, use a copy of the list to control the loop:

for item in the_list[:]:  # slice without parameters creates a copy

Next time, please be sure to use the proper Markdown syntax for your code.

A newbie question, how do you add part of the code to the body of the question/comment?
