The description does not specify that nums will always have one or more numbers.

And it's usually a good practice to check that a value is not zero before dividing something by it.

What is the purpose of the last part? There isn't a case where nums doesn't exist.

Never would have thought of this, nice.

I'm just writing back now. What kind of trick is this?

The addition of 2 Fraction instance should yield a Fraction instance, not its string representation. That one we will have to leave it to str / repr to do the job.

by default will return None nice

There's a math trick that'll help you

Yeah, I think u are right!

You could have left out the != 0 to make it even shorter :)

I am shocked, this is perfect, if comparing to my 30 lines of code

yes, I think u are right!

I believe tuple would be better here in terms of memory usage

Thx bro! ;)

Thanx bro! ;)

love this answer.
