Question

on.ca i.cmd med to u nunaown C eSA COwPA 20 or 2. Write a function that takes a single list of characters as argument and returns a new list of integers as a return value. The list returned must contain the ASCII codes of every uppercase character in the original list in the reverse order from the order they appeared in the original list. You are not permitted to use negative indexing (i.e., the numbers you write in the square brackets to retrieve a value from the list must be nonnegative), and you are not permitted to use any functions other than append, len, and ord. As a clarifying example, if your function was called with the argument ['H', 'e', ", 'L, 'o', "W, 'o', 'r, T, 'D'] it must return the list [68, 87, 76, 72] (because the ASCII codes for 'D', w, 'L, 'H' are 68, 87, 76, 72, respectively) MacBook Pro esc ! & 1 2 3 4 5 6 7 W T U A S F K ck Z C V L O NM CO I R

Answer 1

def ascii_upper(lst):
    result = []
    for ch in lst:
        if 'A' <= ch <= 'Z':
            result = [ord(ch)] + result
    return result


print(ascii_upper(['H', 'e', 'l', 'L', 'o', 'W', 'o', 'r', 'l', 'D']))

[68, 87, 76, 72] Process finished with exit code 0
