Easy question about floats
Im using Python 3

How can I get a float, say 1.0 to print 1.00?
My goal is to make it look like dollars and cents.

Code:
>>> amount = 1
>>> print('{0:.2f}'.format(amount))
1.00

format! thanx a bunch. Worked like a charm.

Can you tell me how it works?
The .2 is for two digits to the right.
What is the 0 and f for? and is there other ways to do this?

0 stands for the first argument in the .format() list, since counting always starts from 0 in Python, and “f” stands for “float”, since that’s how we want that argument to be interpreted.

For further information, you’d better start from the appropriate section in the Python tutorial .
