Python: avoiding fraction simplification

Question

I'm working on a music app' in Python and would like to use the fractions module to handle time signatures amongst other things. My problem is that fractions get simplified, i.e.:

>>> from fractions import Fraction
>>> x = Fraction(4, 4)
>>> x
Fraction(1, 1)

However, it is important from a musical point of view that 4/4 stays 4/4 even though it equals 1. Is there any built-in way to avoid that behaviour?

Thanks!

Answer 1

Yes: make a custom class for it.

Musical time signatures are not fractions, so it doesn't make sense to represent them with a math class.
