In Python you can compare a single element using two binary operators--one on either side:
if 3.14 < x < 3.142: print("x is near pi")
In many (most?) programming languages, this would be evaluated in a way contrary to regular math:
(3.14 < x) < 3.142, but in Python it is treated like
3.14 < x and x < 3.142, just like most non-programmers would expect.
