Python From Scratch Lesson 18 PDF (Python Try Except & User Input & String Formatting)

Welcome to the eighteenth lesson of the “Python From Scratch” series! In this lesson, we will be exploring three important topics in Python programming – try/except statements, user input, and string formatting. We will begin by learning about try/except statements, which allow us to handle errors and exceptions in our code. We will learn how to use try/except statements to gracefully handle errors and prevent our programs from crashing.

Next, we will move on to user input, which is a critical aspect of many programs. We will learn how to accept user input in Python, and how to validate and sanitize that input to ensure that it is safe and correct. Finally, we will explore string formatting, which is a powerful tool for creating dynamic and flexible output in our programs. We will learn how to use string formatting to create complex strings that incorporate data and other variables.

Throughout this lesson, we will be building on the knowledge and skills that we have developed in previous lessons, so it is recommended that you have a solid understanding of Python fundamentals before diving into this one. However, even if you are new to Python, you should be able to follow along with the examples and exercises provided.
