I found this function that I will be saving for later.
def make_it_money(number):
import math
return '$' + str(format(math.floor(number * 100) / 100, ',.2f'))
(I still need more practice to find out how it does what it does, but
I like the end result)
That's total nonsense and overkill! If you really want to do it with a separate function, using
old style:
def make_it_money(number):
return '$%.2f' % number
or using new style:
def make_it_money(number):
return '${:.2f}'.format(number)
But even these functions are unnecessary. Use either of these formatting methods directly in
the print() statement...
So I changed the line in question to:
print (repr(count).rjust(3), make_it_money(payment).rjust(13),
make_it_money(balance).rjust(14))
print('{:3d} ${:<13.2f} ${:<14.2f}'.format(count, payment, balance))
or
print('%3d $%-13.2f $%-14.2f' % (count, payment, balance))
But please, please, PLEASE first go through a real tutorial, and WORK the examples to fix them
in your mind. Questions like these will all be covered there. And you'll learn the language as
a whole instead of trying to be spoon-fed isolated answers. It will be well worth your time.
The tutorial on the official Python web site is a good one (of course there are
many others)
docs.python.org/3/tutorial/index.html
It does appear that you're using Py3, but in case you're using Py2, change the '3' in that URL
to '2'.
(Print formatting is in section 7)

PS. Oops, my bad... I just double checked my suggestions, which left-justified the values, but
I see you want them right-justified (which keeps the decimal points lined up). This complicates
it a bit to keep the dollar-sign butted up against the value, and it makes it necessary to use
that make_it_money() function I said was unnecessary. But it's still unnecessary by using a
little different finagling... Try either of these versions:
print('{:3d} {:>13s} {:>14s}'.format(count,
'$' + str(round(payment, 2)), '$' + str(round(balance, 2))))
print('%3d %13s %14s' % (count, '$' + str(round(payment, 2)), '$' +
str(round(balance, 2))))
