The body of your for loop only rebinds the loop variable. It's not
appending to a new list or modifying listOfNumChars. As to the latter
list, it's redundant since a string is iterable.
The following snippet creates the list [4, 5, 5]:
num = 455
numlist = []
for c in str(num):
numlist.append(int(c))
or using a list comprehension:
numlist = [int(c) for c in str(num)]
or using map:
numlist = list(map(int, str(num)))
