Problem of my code

code: print('one, \'two\',\"three\",four\\five\\n\t once, \'I\' caught a fish\n\t\t\'//alive\\\' ')

I don't know what the problem is but the very last character ' gives an error. If I remove just one ' from the last the code runs but the result doesn't match with the right answer. I hope that you will fix the code and explain it to me.
