Write a function called ascii_caps() that takes a single list of characters as the input
parameter and returns a new list of integers that contains the ASCII codes of the uppercase
characters in the input list.
Sample run,
>>> print(ascii_caps(['H', 'e', 'l', 'L', 'o', 'W', 'o', 'r', 'l',
'D']))
[72, 76, 87, 68]
Note that the ASCII codes for H', L', 'W', 'D' are 72, 76, 87, and 68, respectively.
Hint: you may want to use ord() and chr() functions in your solutions.

• prints the total number of characters in the string
• prints the total number of words in the string
