THE WALRUS OPERATOR IN PYTHON 3.8

Date: 29/01/2020

Introduction

Walrus Operator is another name for Assignment Expressions. I will explain in detail in this article.

Assignment Expressions are written with a new notation which is colon followed by equal to expression ( := ) . It allows you to assign a value to a variable and check conditions for that variable in the same expression.

For Example, Lets find out the given number is odd or even

if((number:=27)%2==0):
   print("Given number is even")
else:
   print("Given number is odd")

Here is the Output :

Advantages of using the assignment expressions is we can directly assign a value to the variable and checks for the condition is satisfied or not at the same time.

Whereas in previous python versions , we have to assign a value for a variable separately and checks the condition by using that variable.

For Example , In python 3.7

number=27
if(number%2==0):
   print("Given number is even")
else:
   print("Given number is odd")

Walrus Operator reduces the code lines and making things easier
