Chaining comparison operators in Python
Checking more than two conditions is very common in Programming Languages. Let say we want to check below condition:
Most common syntax to do it is as follows:

In Python, there is a better way to write this using Comparison operator Chaining. The chaining of operators can be written as follows:
According to associativity and precedence in Python, all comparison operations in Python have the same priority, which is lower than that of any arithmetic, shifting or bitwise operation. Also unlike C, expressions like have the interpretation that is conventional in mathematics.

Chaining of comparison operators
One of the things I enjoy about Python is that some of its features make so much sense that you don't even notice that you are using a feature until someone points out that such code wouldn't work in other languages. One such example is comparison chaining! Look at this snippet of code and tell me if it doesn't look natural:

When Python sees two comparison operators in a row, like in a , it behaves as if you had written something like , except that b only gets evaluated once (which is relevant if b is an expression like a function call).

In my opinion, this features makes a lot of sense and does not look surprising. Instead, now I feel kind of sad that most languages do not have support for this behaviour.

Another example usage is for when you want to make sure that three values are all the same:
