Help with Exception to error

[micseydel]

You only need to change the last block of code you provided. Wrap the four lines within the function in a try, and then catch the KeyError.

I suspect that's not really what you want though. For one thing, you can replace code like

poke['iv_atk']

with

poke.get('iv_atk', None)

That aside, I find it weird that a Pokemon would not have those IVs. You probably should prevent that input being provided to that function, rather than making the function tolerant of bad input.
