I have a function taking float arguments (generally integers or decimals with one significant digit), and I need to output the values in a string with two decimal places (5 -> 5.00, 5.5 -> 5.50, etc). How can I do this in Python?

>>> '%.2f' % 1.234 '1.23' >>> '%.2f' % 5.0 '5.00'
The result of the operator is a string, so you can store it in a variable, print etc.
