Question

I have a question relating to the output of a program.

 def writeOutput():
    output.write(str(gallons) + '\n')
    output.write(str(usage) + '\n')
    output.write(str(sewer) + '\n')
    output.write(str(tax) + '\n')
    output.write(str(total) + '\n')
    output.write('_______________________' + '\n')

This is my write to file function.
Does anybody know where I can look to find out how to write 123.45 as “123 dollars 45 cents” with dollars and cents spelled out like that?

Thanks!

Answer 1

If you have amount stored as a float(*), you can use the % formatting operator as follows:

"%d dollars %d cents" % (int(amount), int(amount * 100 % 100))

or

dollars = int(amount)
"%d dollars %d cents" % (dollars, int((amount - dollars) * 100))

(*) Which you should never do in a real financial app, since floating point is prone to rounding errors; use the Decimal module instead.
