Once You Pop

I'm sorry, but I'm not sure where to go from here..

pop.py 
def pop(lst, ind):
    try:
        lst.pop(ind)
    except IndexError:
        return "Invalid Index"
    else:
        return lst.pop(ind)

Hey Trenton Spears, you are so close!

return lst. Running pop() results in the item popped, so running pop again returns the second popped item.

Post back if you need more help. Good luck!!!

Ahh I see. You wanted me to remove .pop(ind) from the return lst.pop(ind) return statement. Thanks Chris, you're Batman!
