Python If Statements: How to Use Them for Maximum Effect

Share This Post

Programming is all about making decisions. The Python if statement allows you to make decisions based on certain conditions. In this tutorial, we will show you how to use the if statement in Python, and explain the different ways that it can be used.

We will also provide some examples so that you can see how it works in practice.

So let’s get started!

Python If Statements

If you’re a Python programmer, you’ve probably used if statements before. But are you using them to their full potential?

If statements are one of the most common constructs in Python and allow you to control the flow of your program based on a certain condition.

For example, you might use an if statement to check if a user has entered a valid username before proceeding with the rest of your program.

If statements can be used in a number of ways, here we’ll focus on two main uses: testing for equality and testing for membership.

== operator

To test for equality, we use the == operator. This will return True if the two values are equal, and False otherwise.

For example:


if x == y:

... print("x is equal to y")

...else:

... print("x is not equal to y")

Operator

To test for membership, we use the in operator. This will return True if the value is a member of the specified sequence, and False otherwise.

For example:


if x in y:

... print("x is a member of y")

...else:

... print("x is not a member of y")

Keep these tips in mind when using Python if statements, and you’ll be able to take your code to the next level!
