Complete the Python program to include a function named print_random_letter, which will take a string as a parameter, and then randomly choose a character from that string and print the letter and its index position in the string. Follow Instructions below.
- Uncomment the line print_random_letter(current_string) in the given code, and define a function by that name
- print a message that tells the user which random letter was selected from the string, and the index position of that letter (see transcript below for examples.)
- ensure that the random letter really is a letter (not a digit, or a space, or a punctuation mark)
- in the event that the string contains no letters, print a message that reads, "Error: The current string has no letters in it."
- Question 1: Suppose we added another function called char_counter that takes two parameters: the current_string, as well as a single character like 'g'. The function would count the occurrences of the the character in the string, and would return an integer with the count. What would the char_counter function call look like?
- Question 2: Is the char_counter function from above fruitful (ie: returns a value) or non-fruitful (aka: a procedure)
- Question 3: Is the print_random_letter from the lab03.py code a fruitful or non-fruitful function?
- Question 4: Why are while loops used in the main function instead of for loops?
