The goal of this homework is for you to practice and understand how to write functions and evaluate expressions. The homework will consist of 5 functions for you to implement. You have been given HW01.py skeleton file to fill out. However, below you will find more detailed information to complete your assignment. Read it thoroughly before you begin.
Hidden Test Cases: In an effort to encourage debugging and writing robust code, we will be including hidden test cases on Gradescope for some functions. You will not be able to see the input or output to these cases. Below is an example output from a failed hidden test case:

Helpful Information To Know
String Formatting
A concept that will be very helpful for this homework is string formatting. String formatting allows you to manipulate strings using variables so that string values can change based on whatever information is stored in the variables. To explore this concept, letʼs look at an example where a user inputs a name and age, and the code prints out the corresponding information:
name = input("What is your name?") age = input("How old are you?")
print("Your name is {} and you are {} years old!".format(name, age))
Rounding Numbers
Python has a built-in function that allows you to round numbers. For example:
Listen
Function Name: listen()
Parameters: N/A
Returns: None
Domino's Time
Function Name: dominosTime()
Parameters: N/A
Returns: None
Description: During the summer, you ordered a lot of food from Domino's. Pizzas are $12, an order of pasta is $6, and chicken wings are $8. Write a function that asks the user how many of each food item they would like, and then print a response telling them what their order total will be. The order total should be an integer.
Tip and Split
Function Name: tipAndSplit()
Parameters: N/A Returns: None
Description: You are hanging out with your friends at home and decide to order some food. The delivery man was really nice, and you want to tip him. Additionally, you want to split the total between your friends after adding the tip to the total. Write a function that takes as an input the order total, the percentage you want to tip the driver, and the number of friends that are splitting the food. Print the tip and how much each friend must pay. All inputs will be positive integers. Round all outputs to 2 decimal places.
YouTuber
Function Name: youtuber()
Parameters: N/A Returns: None
Description: You are quarantined and you are bored, so you decide to become a YouTuber.
You become successful, and are getting paid from ads. You decide to set up a function that calculates how much money you have made. Write a function that takes as an input the number of videos you have made, how many views each video has, and the amount you are getting paid per view. We assume that every video has the same amount of views. Print how much money you have earned. Round your answer to 2 decimal places.
Bath Bomb
Function Name: bathBomb()
Parameters: N/A
Returns: None
Description: In order to relax before your classes pick up, you decided to take a bath. Before dropping the bath bomb, you decided to measure the volume of it.
Write a function that asks the user what the radius of the bath bomb is, and then calculate the volume of the sphere with the given dimensions. The radius can be a float. Round your answer to 2 decimal points.
