In Python 3.8, we will be able to use assignment as a part of the large expressions. It has a new syntax :=

‍
Examples:

1. if-else block

Python3.8

‍‍

< Python3.8

2. In while-loop:

Python3.8

< Python3.8

here we save one line by using the Walrus Operator.


3. In for-loops:

Python 3.8

< Python 3.8

Notice that this is not a good practise as we need to call call_some_function(number) twice in the comprehension.
