didn't worked at the first time

THIS PROVES MY BRAIN IS BETTER THAN A COMPUTER!

Had exactly this (i thought) and didn't pass 1 (out of dozens of test ran)... weird...

I have a similar solution, however since isupper() has some issues with uncased characters from unicode I dont think this should be the best practice for python.
inp.upper()==inp seems more reliable IMO.

This solution does't work with non-alphanumeric characters.

@rowcased I c. Thank you. I first want to comment "no Brainer" for this question. Then when I clicked 'attempt' twice and twice it failed because it had a special character in the fixed tests.
I reread the question and realized it said, if input didn't have any letters, have to return with all caps.

That's why I was surprised to see how this code went thru.

no, you can see all 4 sample tests. when you hit attempt, there will be fixed tests and then random tests.

I had to change this code because for me this one didn't pass one special character. Is our final sample tests randomly picked?

Always load libraries at the beginning of your code. The reason is two-fold: those reading your code know exactly what libraries you are using, and it increases the efficiency of your functions (as the function would have to check if that library was loaded everytime it was called).

Doesn't work with special characters.

I had the same thing happen to me, it took about three iterations of the "Attempt" button to finally let me pass.

I didn't think that it could be because of the special characters, but I guess it's the only thing that makes sense.

wow didn't notice this code exists

I have a more basic question. Is it better to import the library before the function or in the function? Normally I call it in the function, but for more complex problems I would load it at the start.
