Run and test this Repl using . this link Getting Started Before writing a line of code, let’s write a pseudo code for the process of building the app: The tip calculator will have a message welcoming you to use the app Allow the user to enter the amount of the bill Give users the option to choose the amount of tip to give An input to enter the number of people to split the bill Next, calculate the bill to show how much each person pays Finally, format and round the amount to pay to two decimal places Creating a Tip Calculator in Python A tip calculator is the best application you can have and use when going out as it is accurate with precise calculations. Building this tip calculator will be done in Python. Create a file called and paste the following code: tip_calculator.py # tip_calculator.py

print("Welcome to the tip calculator!")
bill = float(input("What was the total bill? $"))

tip = int(input("How much tip would you like to give? 10, 12, or 15? "))

num_of_split = int(input("How many people to split the bill? "))

calculate_bill = bill * (1 + (tip/100)) / num_of_split

final_amount = "{:.2f}".format(calculate_bill, 2)

if tip == 10:
        print(f"Each person should pay: ${final_amount}")
elif tip == 12:
        print(f"Each person should pay: ${final_amount}")
else:
        print(f"Each person should pay: ${final_amount}") The following occurs in the code block above: The bill variable tells the user to enter a float number that accepts decimals using the input prompt The and variables also allow users to provide the value they desire according to the tip percentage and the number of people. tip num_of_split The is an operation using to calculate how much each person pays from the declared variable result output calculate_bill PEMDAS Next, round/format the bill result to two decimal places to ensure it reads like a currency.
