Let’s Revisit

♦ The primary way to get data from the user into your Python program is through the built-in input() function.
♦ The input() function can accept an optional string argument, known as a prompt.
♦ print() is used to display output to the console.
♦ Errors are an inevitable part of programming. Instead of avoiding them, it's important to learn how to read and understand
error messages.
♦ Syntax errors, also known as parsing errors, are the most basic kind of error.
♦ Run-time errors, also known as exceptions, occur while the program is running.
♦ To prevent runtime errors from crashing your program, Python provides a way to catch and handle them.
♦ Logical errors are the most challenging to diagnose.
