Came to say that, hyper clever really.

What a great tip! Thanks man!

Yes, both good suggestions! Thank you.

I agree. Also you could move the dict outside the function, so the dict wouldn't be created every function call.

Less readable and slower.

I think he means that instead of typing the alphabet yourself as a variable, use the already builtin one to avoid unnecessary errors ( which lead to bad code). I think!

I'm sorry but what is a magic number, and why are strings the experts of bad codes?

Seriously not trying to be a smart aleck here. It seems like you've just improved an inefficient approach. You're level 3 so beyond me python-wise. What made you choose this approach over ord()?

Maybe because it's truncating, not rounding?

But it's less readable.

100%

import everything
print('^^')

No big advantages I think. You may change to "elif" if you think that is clearer. I use consecutive "if"s just because I think that is neater.

it's longer but it's better: isinstance takes care of inheritance of the iputs. Not type.
