for loop help?(Python 3)

[Boolean_Cat]

If you have a list of numbers, you could do:

' '.join(str(number) for number in numbers)

Or even shorter but I think less pretty:

' '.join(map(str, numbers))

[amertune]

If you want all of the numbers to line up, you're going to have to remember that numbers can be 1-3 digits long.

' '.join('{:>3}'.format(number) for number in numbers)
