Hello all, I am up to LISTS chapter in Python course and came to this challenge which confused me a bit.
Our next function will remove all elements from a list with an index within a certain range. The function will accept a list, a starting index, and an ending index. All elements with an index between the starting and ending index should be removed from the list. Here are the steps:
1. Define the function to accept three parameters: the list, the starting index, and the ending index
2. Get all elements before the starting index
3. Get all elements after the ending index
4. Combine the two partial lists into the result
5. Return the result
Now I wasnt sure how to do this but the solution they provided is:
def remove_middle(lst, start, end): return lst[:start] + lst[end+1:] print(remove_middle([4, 8, 15, 16, 23, 42], 1, 3))
This can be solved using one line of code if you combine and slice the lists at the same time. Slicing allows us to get the segments of the list before and after the index range and the operation
+allows us to combine them together.
I am abit confused what is the longer version of the code and steps. Is someone can enlighten me.
