Python? Use "print..." in your code.

can you pls kindly elaborate on how to print the input?

and generally how to access the test case data, if possible? couldn't find any references in the wiki, pardon me if i wasn't thorough enough.

(got the same error message)

Thanks a bunch!

normally when you search for a key that does not exist in a list you will get an error like that

Printing the input is always the thing to do:-)
