Boolean confusion

[Frantisek Fuka]

Can anyone please explain why these two give different results in Python 
2.3?

 >>> 'a' in 'abc' == 1
False
 >>> ('a' in 'abc') == 1
True

I know it's not a good idea to compare boolean with Integer but that's 
not the answer to my question.

(yes, that IS my real name)
(and it's pronounced "Fran-tjee-shek Foo-kah")
