A simple example

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.
