已实现整数位数统计，如何添加执行后用户续行询问功能？

Got it, let's get this sorted for you! The core issue here is wrapping your existing digit-counting logic in a loop that keeps running until the user chooses to stop. Here's how you can adjust your code to get the exact flow you want:

def countDigits(n):
    return len(str(n))

# Set a flag to control if the program keeps running
keep_going = True

while keep_going:
    num = int(input("Enter a number: "))
    # Show the digit count result first
    print("The number of digits for:", num, "is:", countDigits(num))
    
    # Ask user for continuation, with input validation
    while True:
        choice = input("Do you want to continue? Enter 1 for yes, 0 for no: ")
        if choice == "1":
            keep_going = True
            break
        elif choice == "0":
            keep_going = False
            break
        else:
            print("Oops, that's not a valid input! Please enter 1 or 0.")

Let's break down how this works: #

• Outer Loop: The while keep_going loop ensures the program repeats the digit-counting process until the user says "no".
• Result First, Prompt Second: Right after printing the digit count, we immediately ask the user if they want to continue — exactly the order you wanted.
• Input Validation: The inner while True loop makes sure we only accept valid inputs (1 or 0), so the program won't break if the user accidentally types something else.

Give this a test run: it'll show the digit result first, then prompt you to either enter a new number or exit. Perfect!
