I think part of the problem here is that you don't understand the
expression.
The expression:
15 <= x < 30
contains two conditions:
15 <= x
x < 30
For the whole expression to be true, both conditions must be true, hence
the equivalence is:
(15 <= x) and (x < 30)
to test this in python command line, see if the two different expressions
give the same result for a suitable range of values of x:
for x in range(50):
if not (15 <= x < 30) == ((15 <= x) and (x < 30)):
print "discrepancy"
or
for x in range(50):
if (15 <= x < 30) == ((15 <= x) and (x < 30)):
print "ok"
