How to make float values in Python display .00 instead of .0 ?

Question

Simple question, sorry I can;t figure this out. I have some numbers that are made by float(STRING) and they are displayed as xxx.0, but I want them to end in .00 if it is indeed a whole number. How would I do this?

Thanks!

EDIT:

Python saiys that float doesn't have a cal 'format()'

Answer 1

>>> '%.2f' % 2.0
'2.00'

Answer 2

Also:

>>> "{0:.2f}".format(2.0)
'2.00'

Answer 3

If you do not like the numbers to be rounded, you need to do little more:

>>> "%.2f"  % 1.99999
'2.00'
>>> "%.2f"  % (int(1.99999*100)/100.0)
'1.99'

Answer 4

>>> "{0:.2f}".format(2)
'2.00'
