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

i dont get it. I'm guessing i need to use a for loop but how do i do it?

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))

the_list = [x for x in the_list if ...]

You don't need a loop. You can remove each item individually:

the_list = ["a", 2, 3, 1, False, [1, 2, 3]]


# Your code goes below here
the_list.insert(0, the_list.pop(3))

#the_list = [x for x in the_list if ...]
the_list.remove("a")
the_list.remove(False)
the_list.pop()

thanks alot.

im stuck on this now

Now, make the_list contain only the numbers 1 through 20 by using .extend().

the_list = ["a", 2, 3, 1, False, [1, 2, 3]]
new = the_list.pop(3)
the_list.insert(0, new)
# Your code goes below here
the_list.remove(False)
the_list.remove("a")
del the_list[len(the_list)-1]
