Challenge

Easy

Handle the option to calculate the total and average expense (3).

If the expenses list is empty, output:

No expenses recorded yet.

Otherwise, output the list in the following format:

Total expense: 600.0
Average expense: 200.0

Assuming the expenses entered before were 300, 200 and 100. (In that order!)

Try it yourself

print("Welcome to the Daily Expense Tracker!")

# Display menu once
print("\nMenu:")
print("1. Add a new expense")
print("2. View all expenses")
print("3. Calculate total and average expense")
print("4. Clear all expenses")
print("5. Exit")

# Initialize an empty list to store expenses
expenses = []

while True:
    # Get user choice
    choice = input()
    
    if choice == "1":
        # Add a new expense
        amount = float(input())
        expenses.append(amount)
        print("Expense added successfully!")

    elif choice == "2":
        # View all expenses
        if len(expenses) == 0:
            print("No expenses recorded yet.")
        else:
            print("Your expenses:")
            for i in range(len(expenses)):
                print(f"{i + 1}. {expenses[i]}")

    elif choice == "5":
        # Exit the program
        print("Exiting the Daily Expense Tracker. Goodbye!")
        break
