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

This is the same solution as you have probably seen already, but by doing it this way it's more clearer:

>>> num = 3.141592654

>>> print(f"Number: {num:.2f}")
