Write a statement that calls the recursive function backward

Write a statement that calls the recursive function backwards_alphabet() with parameter starting_letter.

def backwards_alphabet(curr_letter):
    if curr_letter == \'a\':
        print(curr_letter)
    else:
        print(curr_letter)
        prev_letter = chr(ord(curr_letter) - 1)
        backwards_alphabet(prev_letter)

starting_letter = \'f\'

\'\'\'Your solution goes here\'\'\'

Solution

def backwards_alphabet(curr_letter):
if curr_letter == \'a\':
print(curr_letter)
else:
print(curr_letter)
prev_letter = chr(ord(curr_letter) - 1)
backwards_alphabet(prev_letter)
starting_letter = \'f\'
backwards_alphabet(starting_letter);
