What would be the output of the following code? def get_letter_index(letter, string): returns the index of letter in string, OR if letter is not found in string, prints that information instead. If the letter occurs multiple times, this returns only the first index where the letter is found. Index where the letter is found for i in range(len(string)): if string[i] == letter: return i #if execution reaches this point, we must not have found the letter print(letter, "not found in", string) my_string = "alpha" p_index = get_letter_index("p", my_string) print(my_string[p_index])
