Remove items from a list while iterating using python programming

Hint:

• Get the list's size
• Iterate list using while loop
• Check if the number is greater than 50
• If yes, delete the item using a del keyword
• Reduce the list size

Solution1:Using while loop

number_list = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100]
i = 0
# get list's size
n = len(number_list)
# iterate list till i is smaller than n
while i < n:
    # check if number is greater than 50
    if number_list[i] > 50:
        # delete current index from list
        del number_list[i]
        # reduce the list size
        n = n - 1
    else:
        # move to next item
        i = i + 1
print(number_list)

Solution2:Using for loop and range()

number_list = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100]
for i in range(len(number_list) - 1, -1, -1):
    if number_list[i] > 50:
        del number_list[i]
print(number_list)
