The first answer was `if in `, which is valid Python but not valid Go. The second was `if strings.Contains(, )`. There is a `strings` package that has a `Contains` method, but it's to check if a substring is in the input string.
So I would suggest a healthy dose of skepticism when asking programming questions to this thing. Wondering what other types of questions I should try. What use cases are you actually getting useful results from?
