Here is a clue.

 True
 py> 'E' == 'E'

The thing you're looking for is case-folding, or possibly
lower-casing. You should be able to find what you want with that. :)

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.

AND each character coming in from the keyboard with $DF before adding it to 
the comparison buffer.  Makes it all uppercase.  Then compare it to the 
uppercase YES.

It's not working for me.

>>> ''.join(chr(ord(c) & 0xdf) for c in 'ναί') == 'ΝΑΊ'
False
>>> ''.join(chr(ord(c) & 0xdf) for c in 'ναί')
'\x9d\x91\x8f'

Hello, the 1970s called and want their hairstyles back! That is *terrible*
practice in a modern high-level language. Use the library functions. They
will take proper account of the character set being used (which you
shouldn't even have to know for a task like this, let alone make unsafe
assumptions about).
