	Except that Python does short-circuit evaluation; your scheme will
fail in some situations:

>>> x = 0
>>> if x != 0 and 32 / x > 4:
... 	print "we passed"
... 	
>>> c1 = x != 0
>>> c2 = 32 / x > 4
Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
ZeroDivisionError: integer division or modulo by zero
