我可以/如何使用while＆amp;如何跳回特定的代码行；如果在一起？

Question

我已经编写了我的代码以正常工作，但是如果用户选择尝试其他输出，我想跳过介绍性消息。例如，如果用户选择生成不同的密码，我希望返回第11行（输入长度​​要求的请求），而不是第8行。（该行欢迎用户进入程序）。

import random
import string
import sys

another = True

while another:
8    print("Welcome to the Password Generator!")

# ask user for password length requirement
11    length = int(input("How many characters does your password require?: "))

# initialize character types

    lower = string.ascii_lowercase
    capitalize = string.ascii_uppercase
    nums = string.digits
    symbols = string.punctuation

# combine all char types
    combine = lower + capitalize + nums + symbols

# randomize character types and add length requirement
    randomization = random.sample(combine, length)

# construct the secure password
    secure_pw = "".join(randomization)

# display password
    print(secure_pw)

    another = input("Would you like to generate a different secure password?: ")
    while True:
        if another == 'yes':
            generate = True
            break
        elif another == 'no':
            generate = False
            sys.exit()
        else:
            another = input('Invalid response! Enter "yes" to continue or "no" to exit: ')
