如何让用户选择重新进入循环

每个人

我有一些代码，我不确定如何根据用户的回答停止循环。如果请求为是，则继续循环，但如果回答为否，则打印最后的语句。感谢所有帮助完成这项任务的人。

    import random

char = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890!#$%&*/\(')"

while 1:
    password_len = int(input("How many characters do you want your password? "))
    password_count = int(input("How many passwords do you want? "))

    for x in range(0,password_count):
        password = ""

        for x in range(0,password_len):
            password_char = random.choice(char)
            password = password + password_char

        print("Here is your password:", password)

        ans = input("Do you need more passwords? ").lower()

        if ans == "yes":
            
            
        else:
            print("Thank you for your service, goodbye.")
