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

what is the purpose of the ".remove" function?

Can't I just delete what I want to delete manually?

messy_list = ["a", 2, 3, 1, False, [1, 2, 3]]

# Your code goes below here
messy_list.insert(0, messy_list.pop(3))
del messy_list[3]

remove function removes the first matching value, not a specific index. del removes the item at a specific index

for example: x = ['a', 'a', 'b'] x.remove('a') => will delete the first 'a' in the list but what if you want to delete the second 'a' in the list, then you have to use del to target that item del x[1] happy coding :)

What if you had 1000s of items or you were working with data that was continually updated on a periodic basis?
