3) What is a flaw with this code to remove all the "4" values from a list?

nums = [1, 3, 5, 4, 7, 8, 4, 4, 9, 1, 12] nums.remove(4)

------------------------------------------------------------------------------

4) What is the flaw with this code to remove all the "4" values from a list?

nums = [1, 3, 5, 4, 7, 8, 4, 4, 9, 1, 12]

spot = 0

while spot < len(nums):

if nums[spot] == 4:

del nums[spot]

spot = spot + 1

Answer #1

Answer 3: It will remove the only first occurence of the 4. so it will not remove all 4's from the list

Answer 4:if we have two 4 consquetively than it can't remove it becuse we are increasing the spot here so when remove 4 size of list decrease and indexes changes

so if we have two 4's side by side by than we will skip the other 4
