the expression looks like this:
x & 528 or x in l

if x & 528:
return True
elif x in l:
return True
else:
return False
where x & 528 is the bitwise combination of x with 528.
Obviously the code you quote is taking the logical inverse
of this expression - "while not (...)"

I saw a strange python code in pygame project. What does "while
not(x&528or x in l):" mean? Below code works in python2.5, so "x&528"
is not HTML strings.
