Question

Define a function funD2(...) which receives a list lst that contains single letters, single digits and single special characters (and the list contains at least one element of each type). The function returns a string that contains the last letter and the last special character of the list, where each is repeated as many times as the sum of all digits in the list.

As an example, the following code fragment: lst = ["a","b","c", 1, 2, "$","%"]
print (funD2(lst))
should produce the output:

ccc%%%

Answer 1

def funD2(lst):
    last_letter = ''
    last_special = ''
    total = 0
    for ch in lst:
        if type(ch) == int:
            total += ch
        elif ch.isalpha():
            last_letter = ch
        else:
            last_special = ch
    return (last_letter * total) + (last_special * total)


# Testing the function here. ignore/remove the code below if not required
lst = ["a", "b", "c", 1, 2, "$", "%"]
print(funD2(lst))
