def remove_middle(lst,start,end):
  del lst[start: (end+1)]
  return lst

This may not be the solution they used but it works.
Pretty sure del was talked about earlier. Either way its self explanatory.
Google is your friend, this is a class not a instant pass to learn Python in 24 hours.
You will need to ask questions.

#Write your function here

if start < len(lst):
one_step = lst[:start]
if end <= len(lst):
two_step = lst[end+1:]
return one_step + two_step
#Uncomment the line below when your function is done
print(remove_middle([4, 8, 15, 16, 23, 42], 1, 3))

My dirty solution? Here it is:

def remove_middle(lst, start, end):
  del(lst[start:end+1])
  return lst

Yeah, not very smart, but it worked.

This assignment, more so than most, shows how many ways there are to complete a task!

Solution using pop()

def remove_middle(lst, start, end):
  for i in range(start,end+1):
    lst.pop(start)
  return lst

Am I the only one who didn’t understand what the heck the instructions were saying on this task or the previous one?
