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

please help im stuck

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

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

  1. A note about your code: list(the_list) is redundant. the_list is already a python list so there is no need to call the list() function on it. You can simplify this line to be just for item in the_list:
  2. At the end of your script, the_list should be [1, 2, 3]. You need to add 4-20 to the list. I would recommend looking up the range() function and then think about how you can combine it with the_list using the .extend() method.

Good luck learning Python!
