Hello,
can someone explain this task please?

Create a function named remove_middle which has three parameters named lst , start , and end .

The function should return a list where all elements in lst with an index between start and end (inclusive) have been removed.

and why this is the solution to it:
def remove_middle(lst, start, end):
return lst[:start] + lst[end+1:]
