trying to print a sorted dictionary but it gives me syntax error

Question

Looking over some class notes and I came across this piece of code. I copied it exactly from the notes but when i run it, it gives me a syntax error on the final line. Anyone able to point out the mistake?

    phone_book = { 'joe' : '086 7346659',
       'jimmy' : '085 2313872',
       'cindy' : '087 9452238' }

    print(sorted(phone_book.items()))
    for k, v in sorted(phone_book.items()):
       print(f' {k} ---> {v}')

What version of Python? f-strings were introduced in Python 3.6 and would be a syntax error in older versions. The code works fine in Python 3.9. — Mark Tolonen, Apr 03 '21 at 17:35
@MarkTolonen yep that was the mistake , I was running 2.7. Thanks for your help — genuine_choco_milk, Apr 03 '21 at 17:37
Try this instead of the last line. print(' {} ---> {}'.format(k, v)) — Nicholas Hunter, Apr 03 '21 at 17:37

I don't know if this will help. Your code seems to work fine on python3.7 through python3.9.

Though it doesn't work on 2.7. Try this instead.

phone_book = { 'joe' : '086 7346659',
       'jimmy' : '085 2313872',
       'cindy' : '087 9452238' }

print(sorted(phone_book.items()))
for k, v in sorted(phone_book.items()):
    print(k+' ---> '+v)
