[Tutor] more problems, my final questions

Hi Kyle,

By the way, the statement above translates to:

    "if begin is equal to the string 'Yy', do this:..."

because if two literal strings are together like that, they'll stick
together.  For example:




> I'm asking because I recently added:
> else begin in "CustomcustomCUSTOM":

I think that you're trying to find if there's a substring of begin within
that "CustomcustomCUSTOM" string.  If so, there's another way of
expressing this:

###
def substring(word, sentence):
    return sentence.find(word) != -1
