CONDITIONAL Statements in Python (IF, ELIF, ELSE, Nested, Ternary Operators) - Python for Beginners

Описание: 🎓 Welcome back to Digital Academy, the Complete Python Development Tutorial for Beginners, which will teach you How to control the execution flow in your program, using Expressions and Conditional Statements in Python: IF, ELIF, ELSE - and more!

▬▬▬▬ 📖 Content ▬▬▬▬

🖥️ Everything you have seen so far, has consisted of sequential execution, in which statements are always performed, one after the next - and exactly in the order you specified, explicitly!

But the World is often more complicated than that. Frequently, a program needs to skip over some statements, execute a series of statements, repetitively - or even choose between alternate sets of statements, to execute. And this is where the core concept of Control Structure comes in, so you can control which instructions are executed, in your program - and alter its behaviour.

In programming languages, most of the time you want to control the execution flow of your program, since: you want to execute some set of statements, only if the given condition is satisfied. And a different set of statements, when it is not satisfied. Please, also note that Conditional Structures are also known as: Decision-making statements!

A Decision, is when a program has more than one choice of actions, depending on a variable's value. In the real World, you commonly must evaluate information around you, and then choose one course of action or another, based on what you observe (e.g traffic light)

Luckily, when your application needs to make such decisions in Python, the IF statement is how you perform this sort of decision-making. And it allows conditional execution of a statement, or a group of statements, based on the value of a boolean expression. Then comes IF, ELSE, and ELIF - so you can add more branches to your program.

🎯How to control the execution flow of your program, so you can change its behaviour based on an expression, or variable's value? In this video, you will discover conditional statements: If, Else, Elif. You will then learn how to combine them in Nested Conditionals, and How to use Ternary Operators!

Let's play this video, stick around and watch until the end! 👍🏻
