Need clarification on this .remove() problem
The question asked to:
Use .remove() and/or del to remove the string, boolean, and list members of the_list.

I'm wondering why the list data type ([1,2,3]) is still on the list after this for loop?
the_list = ["a", 2, 3, 1, False, [1, 2, 3]] # Your code goes below here the_list.insert(0,the_list.pop(3)) for value in the_list: if type(value) is list or type(value) is bool or type(value) is str: the_list.remove(value)
