3 옵션을 처리하여 total 및 average expense를 계산합니다.

expenses list가 비어 있으면 다음을 출력합니다:

No expenses recorded yet.

그렇지 않으면 다음 형식으로 목록을 출력합니다:

Total expense: 600.0
Average expense: 200.0

앞서 입력한 expenses가 300, 200, 100이라고 가정합니다. (이 순서대로!)

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

    # Get user choice
    choice = input()

        # Add a new expense
        amount = float(input())
        expenses.append(amount)
        print("Expense added successfully!")

    elif choice == "2":

            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!")
