@mayalavi In your function you must add some method to print function's solution. I dont know waht is the command in pythom, maybe "print". And when you will be click test you see the results of your function. Second you print the test values. For example you need to create function that accepts parametres "p". But you dont know values of they. Write in the first line of your function print command and you will see what values did you accept. After this you can understand what you must to do with it.

So what is that symbol. In browser my code return false with "123 " param. But not here.

Maybe i need help. I've passed all test except one. It Expected: 4, instead got: 3. I cant understand what is the problem, maybe u can write the task value for this test? Because it pisses me off)))
