python - 如何正确使用登录系统

Question

我找到了登录功能，但是如何检查登录是否已完成？这是我的代码:

def login():
    username = input("Please enter your username")
    password = input("Please enter your password")  
    for line in open("accounts.txt","r").readlines(): # Read the lines
        login_info = line.split() # Split on the space, and store the results in a list of two strings
        if username == login_info[0] and password == login_info[1]:
           print("Correct credentials!")
           return True
        print("Incorrect credentials.")
    return False

while login() == False:
    login()

Answer 1

def login():
    username = input("Please enter your username")
    password = input("Please enter your password")  
    for line in open("accounts.txt","r").readlines(): # Read the lines
        login_info = line.split() # Split on the space, and store the results in a list of two strings
        if username == login_info[0] and password == login_info[1]:
           print("Correct credentials!")
           return True
        print("Incorrect credentials.")
    return False

while login() == False:
    login()
else:
    print("Your in")

在 while 循环中使用 else 语句
