Need a hint about using range.

I have looked at help for Python, but don't understand how to use range in this challenge. Is that what I need to use? Hints appreciated!

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.remove("a")
the_list.remove(False)
del the_list[3]

the_list.extend(range(4, 21)

Hi Kathleen,

You're close: looks like you're missing a closing parenthesis (every opening parenthesis in a statement needs a matching closing parenthesis at some point in the statement.)

the_list.extend(range(4, 21))

Hope this helps!

Thank you! Sometimes it's hard to see the obvious!
