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

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

Hi Maya,

The wording on this challenge was a little confusing to me also. Just pop the first 1, don't worry about the other 1 in the list at the end.

Removing your last line should pass the challenge. But, try to do it in one line!

Cheers

I was able to do the first task, just not the second one where it asks you to "use .remove() and/or del to remove the string, Boolean, and list members of the_list." Do you know how to do this one?

Indeed, my appologies! remove() takes one argument and will remove the first item found from the list that matches it's argument.

Python Docs list.remove

I don't know of a way to remove / del multiple items from a list in one line.

del can remove a sequence of elements from a list, but still not sure if it's possible to use just one del to remove these three elements.

Python Docs del statement

Using 3 lines to remove / del 3 elements will work just fine.
