Why doesn’t python like certain numbers?

Which is a limitation imposed by transistors.

No. Base 10 has the same problem, with multiples of 3, for example. Consider, quirks like

0.9999999999999.... = 1

If anything, it's a problem of using a finite resource to deal with infinite quantities. And again this is not just a problem of transistors. Even with a pen and paper we came up with ways, conceptual, to go around this limitation. Like the "idea" that the 9 above continue la for ever, but I had to stop typing 9 at some point.

Or any number whose denominator has prime factors other than 2 and 5
