. Write a function called count_upper that returns the number of uppercase characters that appear in the input parameter "my_string". Write a print_percentage that takes a string as its parameter and prints the percentage of uppercase letters in that string. Make sure you use the count_upper function to calculate the uppercase percentage. Use the following formula to find the uppercase percentage: uppercase rate = number of uppercase letters / total number of characters (uppercase percentage is the uppercase rate printed in percentage format) Find the percentage of the uppercase characters in the following strings: "Hello, My Name is ABC." "#012%6jjx: This is NOT GOOD" The output should be as follows: Percentage of uppercase letters in "Hello, My Name is ABC." is: 27.27% Percentage of uppercase letters in "#012%6jjx: This is NOT GOOD" is: 33.33%
