[Baypiggies] What is happening here with true/false comparisons

[Max Slimmer]

Can anyone explain the following:

>>> a = 1
>>> b = 2
>>> alist = [5,6]
>>> print a in alist
False

>>> a in alist == b in alist
False
>>> a in alist == a in alist
False
>>> bool(a in alist) == bool(b in alist)      # this does what we expect
True
>>> c = 5
>>> c in alist == c in alist
False
>>>
