It is not explicitly stated what order key-values have to be returned, although in example it is sorted alphabetically. I don't know many programming languages, but in Python dictionary kept order from 3.6, in C# it is not kept. So maybe some clarification is needed.

The link in the description is dead, could use this instead: https://en.wikipedia.org/wiki/Nth_root#Simplified_form_of_a_radical_expression

idk if this is an issue or my mistake...
i got timed out when i hit the submit button, simple tests worked just fine (~800ms) tho.

p.s. total begginer here

I have changed it.

The output is always the same length, so a tuple is better practice in Python.
Yes, if it's translated into a language that doesn't have tuples, you can do that in that language. But Python has tuples.

I appreciate the feedback. This is my first kata, so I am still learning. Could someone explain why the output type would be better as a tuple? If someone makes a good argument, I will change it.

But the output type really should be a tuple. And why shouldn't it be an issue?

Not an issue.

How is that an issue, though??

Thank You

Updated to Python 3.6, and fixed it so your solution passes the tests by using the correct function name ;)
