Asyncio 不回歡迎 function

Question

我正在學習使用異步函數，在這個練習中，我正在模擬與 IA 的對話。 Everything goes fine until right after the program asks for a name but instead returns to the nice to meet you {} in the welcome function it continues to the create_user() function and when the create_user() function finishes it returns to the welcome function to要求創建用戶。

這是 OUTPUT 即時消息：

>> Hello
>> Who are you?
>> What's your name? Moises
>> Tell me a user name you like: RD
>> Now tell me a password: 1234
>> User created!
>> Nice to meet you Moises!
>> would you like to create a user? y/n y
>> Nice, you have a username {user} and a password {}
>> now you are part of us!
