Display Formating

[scidam]

The problem is in line #9: you pass only one argument to .format method, but 6 expected.
You code could be as follows:

def line_up(roster):
    if not roster:
        print("There is no player in the list. \n")
        return
    for i, row in enumerate(roster):
        print("{:>2}{:10d}{:2d}{:2d}{:2d}{:2d} \n".format(i + 1, *row))

>>>line_up([[1,2,3,4,5], [2,3,4,5,6,7]])

Output:
 1         1 2 3 4 5 

 2         2 3 4 5 6
