fmt_directory_entry = "{counter:>02}. {director:<52} {avg}"

[ClassicalSoul]

What exactly is going on with the {counter:>02} parameter in the fmt_directory_entry assignment? In particular, how is it effected that 0 should be inserted to the left of counter if len(counter) > 2? Is there a way I could make it be an other symbol other than 0, say the letter i?

def print_results():
    fmt_directory_entry = "{counter:>02}. {director:<52} {avg}"
    for counter, director_info in enumerate(top_directors_with_at_least_four(),
                                            1):
        director, rating = director_info[0]

        print(fmt_directory_entry.format(counter=counter, director=director,
                                         avg=rating))
