It's a Python question. I've made the code like above. It's a task that defines a function that compares the size of a fraction.
If you turn it around
1/4 < 1/5 ->> True
It comes out like this. Shouldn't it be 1/4 < 1/5 -> > False? I'm asking you a question because I think the code runs well but it seems strange. What's the problem?
python compare
I thought it was strange, so I looked at the official document .
Specifically, (…)) gt(a, b) is equivalent to a > b, and (…)
To write what you want, you need to define __lt__(self, other).
