用户和密码--使用哪种类型更好，二维数组还是字典？
我试图设计一个程序来匹配用户名和他们的密码。我已经使用了两个独立的列表，但现在我在想2d数组或字典会更好吗? 欢迎任何建议。谢谢
def login():
official_users=['dan','bob','bill']
official_passwords=['snow','golf','dogs']
username=input("Enter your user name: ")
while username in official_users:
print("You are user number:
",official_users.index(username)+1)
position=(official_users.index(username))
print(position)
attempts=0
while attempts<3:
password=input("Enter your password: ")
if password == official_passwords[position]:
print("Log in successfull")
print("Hello",username)
login()
else:
print("Incorrect password")
attempts+=1
print("Attempts left: ",3-attempts)
if attempts==3:
print("Too many attempts!")
login()
print("Unknown User")
login()
login()
