Use .remove and/or del

I have tried this probably 15 different ways, and no matter how I format it, I got an error saying that Task1 is no longer passing (task one is to move the 1 from index 3 to 0).

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')
del the_list[4]
del the_list[5]

Hi,

Looks like your last delete statement is trying to delete from an index that doesn't exist. It should be deleting the entry with index 3.

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

# Your code goes below here
the_list.pop(3) # the_list contains ["a", 2, 3, False, [1,2,3]]
the_list.insert(0, 1) # [1, "a", 2, 3, False, [1,2,3]]
the_list.remove('a')  # [1, 2, 3, False, [1,2,3]]
del the_list[4] # [1,2,3,False]
del the_list[3] # [1,2,3]
