The Walrus Operator (:=) in Python

<p>In this post we&rsquo;ll have a look at Python&rsquo;s walrus operator (<code>:=</code>), which can be used to assign and return a value in one expression. This can sometimes lead to shorter and more readable code, or save compute.</p> <p>Python is a popular programming language known for its simplicity, flexibility, and ease of use. In version 3.8, Python introduced the Walrus Operator (:=), a new feature that allows you to assign values to variables within an expression. This operator is a relatively new addition to the language, and it has quickly become popular among Python developers. In this blog post, we&rsquo;ll explore the Walrus Operator in Python and see how it can be used to write more concise and readable code.</p> <h1><strong>What is the Walrus Operator (:=)?</strong></h1> <p>The Walrus Operator is a new syntax introduced in Python 3.8 that allows you to assign values to variables within an expression. This is particularly useful when you want to use the value of a variable multiple times within the same expression. The Walrus Operator is denoted by the := symbol.</p> <h1><strong>Example 1: Simple Walrus Operator Example</strong></h1> <pre> x = 10 if (y := x + 5) &gt; 10: print(&quot;y is greater than 10&quot;) else: print(&quot;y is less than or equal to 10&quot;)</pre> <p>In this example, we use the Walrus Operator to assign the value of x + 5 to y within the if statement. If y is greater than 10, we print &ldquo;y is greater than 10,&rdquo; and if it&rsquo;s less than or equal to 10, we print &ldquo;y is less than or equal to 10.&rdquo;</p> <p><a href="https://medium.com/@rajputgajanan50/the-walrus-operator-in-python-90532f6ccd8a">Read More</a></p>
