Please ask for help on StackOverflow or the general Python mailing list. Your understanding of the operations is incorrect. "&" is NOT a logical operator ("and" is). It's a bitwise operator on integers. >>> 10 & 10 10 >>> bin(10) '0b1010' The last bit is 0, so when you "&" the result with True (which is equivalent to integer 1) the result is 0: >>> (10 & 10) & True 0 and the integer 0 is treated as False in a Boolean context.

"&" is NOT a logical operator ("and" is). It's a bitwise operator on integers.

>>> 10 & 10
10
>>> bin(10)
'0b1010'

The last bit is 0, so when you "&" the result with True (which is equivalent to integer 1) the result is 0:

>>> (10 & 10) & True
0

and the integer 0 is treated as False in a Boolean context.
