Python Python Collections (2016, retired 2019) Lists Removing items from a list

Not working.

How would you move the 1 to the front?

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

# Your code goes below here
one = messy_list.pop(1)
messy_list.insert(0, one) 

You don't want to put the 1 itself inside of .pop(). Instead, you need to put the index number in there. Your code is taking the 2 and moving it to the front because you said, .pop(1). To move the 1 you would need to do:

one = messy_list.pop(3)
messy_list.insert(0, one)

Let me know if that makes sense!

Ah of course! Thank you Nate, that is so helpful!

Remember that .pop takes an index of not the value of the element you want to "pop."

Try something like messy_list.pop(messy_list.index(1)) instead.

I hope this helps ;)
