Sometimes you want to give your Python script information right when you run it from the terminal, without waiting for it to ask for input.

If you're learning to code, you'll almost certainly encounter the FizzBuzz problem.

Do you remember the Pythagorean Theorem from math class?

When your Python program doesn't work as expected, it's because of a bug, or an error.

Imagine you have a list of phone numbers, but instead of accessing them by a numeric index like 0 or 1, you want to look them up by a person's name.

What if you could solve a big problem by solving a smaller, identical version of the same problem?

So far, your programs have probably read input from the keyboard and displayed output on the screen.

What happens when your program encounters an error, like a user entering text instead of a number, or trying to open a file that doesn't exist?

As your programs get bigger, you'll find yourself repeating the same blocks of code.
