Rounding to two decimal places in Python 2.7?

Question

Using Python 2.7 how do I round my numbers to two decimal places rather than the 10 or so it gives?

print \"financial return of outcome 1 =\",\"$\"+str(out1)         


        

Answer 1

The best, I think, is to use the format() function:

>>> print("financial return of outcome 1 = $ " + format(str(out1), '.2f'))
// Should print: financial return of outcome 1 = $ 752.60

But I have to say: don't use round or format when working with financial values.
