How can I format a decimal to always show 2 decimal places?

Question

I want to display:

49 as 49.00

and:

54.9 as 54.90

Regardless of the length of the decimal

Answer 1

if you have multiple parameters you can use

 print('some string {0:.2f} & {1:.2f}'.format(1.1234,2.345))
 >>> some string 1.12 & 2.35
