“print（password）”只是讓我測驗它是否真的對字串進行了哈希處理，因為這是我第一次做這樣的事情。如何將密碼和用戶名保存到電子郵件中，同樣如何驗證密碼和用戶名？

代替：
def save_users():
f = open("UserDetails.txt", "w")
f.write("Username;{} \nPassword:{}".format(username, password))
f.close
和：
def save_users(username, password):
f = open("UserDetails.txt", "w")
f.write("Username;{} \nPassword:{}".format(username, password))
f.close()
并用save_users(username, password)而不是呼叫它save_users()
