Starting Out With Python 4th Edition - Chapter 5 (Functions) Questions and Answers Graded A+ What does the keyword `def` do in Python? It is used to define a new function. How can you pass information to a function? By providing arguments inside the parentheses when calling the function. Why is it useful to break a program into smaller functions? It improves readability, reusability, and simplifies debugging. What is the scope of a variable defined inside a function? It is local to the function and cannot be accessed outside of it. How can you make a function output something without using `print` inside it? By using the `return` statement and handling the output outside the function. 2 What does it mean to call a function with "positional arguments"? Arguments are matched to parameters based on their position in the function call. What is a default parameter value in a function? It is a value assigned to a parameter that is used if no argument is provided. How can you make a parameter optional in a function? By assigning it a default value in the function definition. What is the difference between `print` and `return` in a function? `print` displays output on the screen, while `return` sends a value back to the caller. How do you document what a function does? By writing a docstring inside triple quotes at the beginning of the function. What happens if you call a function before it is defined? You will get a `NameError` because the function is not yet recognized. 3 What is recursion in the context of functions? Recursion is when a function calls itself to solve smaller instances of a problem. Can a function return multiple values? Yes, by returning them as a tuple or another collection like a list. What is the benefit of using keyword arguments in a function call? They make the code more readable and allow arguments to be passed out of order. How do you define a function with no parameters? By using an empty pair of parentheses after the function name. What happens if you define two functions with the same name? The most recently defined function will overwrite the previous one. Why is it important to test a function after writing it? To ensure it performs the expected task and handles edge cases correctly. 4 How do you pass a list as an argument to a function? By including the list in the parentheses when calling the function. What is the purpose of a helper function? A helper function performs part of a task to support a larger function. How do you ensure a function is flexible to handle various inputs? By using parameters and default values
