非函数实现密码验证重试：如何让IF逻辑重复执行至输入正确

Hey there! Let's get this password retry logic sorted without wrapping the validation into a function. The key here is to use a loop that keeps asking for input until the correct password is entered. Here's how you can adjust your code:

Step-by-Step Implementation #

We'll use an infinite while True loop (don't worry, we'll break out of it once the password is correct) to repeatedly prompt the user for input:

# Assuming userPassword is already defined somewhere above this code
while True:
    userInput = input("Please enter your password: ")  # Prompt for input every loop iteration
    if userInput != userPassword:
        print("I'm sorry, that is wrong please try again. Try to remember capitals!")
    else:
        print("That is correct you may now find out your mobile phone costs!")
        break  # Exit the loop once correct password is entered

mobile_phone()  # Runs only after successful password validation

Key Details to Keep in Mind #

• We move the userInput prompt inside the loop so the user is asked for a new password every time they mess up.
• The break statement in the else clause stops the infinite loop immediately when the correct password is provided, allowing the code to proceed to mobile_phone().
• No function encapsulation is needed here—all logic stays in the main execution flow, exactly as you requested.

This setup will keep showing the error message and prompting for input until the user enters the correct password, then it'll seamlessly move on to the mobile phone cost function.
