处理查看所有支出的选项（2）。

如果支出列表为空，输出：

No expenses recorded yet.

否则，按以下格式输出列表：

Your expenses:
1. 23.1
2. 35.5
3. 99.99
4. 15.2

假设之前输入的支出依次为 23.1、35.5、99.99 和 15.2。

亲手试试

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