Your code mutates the input. The kata description says you shouldn't.

l=a.split('')

ValueError: empty separator

Also, I have no idea what you second if statement is about.

Your whole approach seems to be prone to errors, I'd actually recommend coming back to this one after solving more katas first. Also, when you post code, use proper code formatting, and read this troubleshooting FAQ first.

Literally the first example...

solve("code*s","codewars") = true, because we can replace the asterix(*) with "war" to match the second string.

Your code would return False. Your code just removes the asterisk, but it can be replaced with any other string to match the strings, if possible.

Your solution is incorrect, the task isn't so simple. Read the description again, especially the first example. Also, add spoiler flag next time plz.

Because 2 is a prime

why isnt 12 in the array ? is not a prime..

Is 19 a prime?
