nice

Your line with string.lower() is not exactly correct, you need to poke a bit around this line. The way it is now, it has no effect.

Got it, that totally makes sense. Thanks so much.

You are printing the value, your function doesn't have a return value so it returns None. The assertion message is saying Your function returned None, but it should have returned False (or True)

You need to return the return value, not print it.

I'm confused on whether my output should just be true or false or whether I am supposed to include the explanation like the test cases have. My function is evaluating each string correctly, but then it keeps saying, "None shouod be False (or True)." I feel like I must be missing something obvious.

Codewars is the best.

Your last return isn't where it should be. (And please say the language you use next time you ask for help.)

I have this problem : "Response received but no data was written to STDOUT or STDERR.", someone can help me please ? :/
