Take the user's input, strip off any whitespace from the beginning and 
end, then fold the case to a consistent known form, e.g. lowercase.

# in Python 3.x, use input() rather than raw_input()
result = raw_input("Answer my question! ")
result = result.strip().lower()
if result == "yes":
    ...


For English words, like "yes", converting to lowercase will do the job. 
But if you are using Python 3.3 or better, then I recommend you use 
casefold() instead of lower() since that is smarter about converting case 
when you have non-English characters.
