下面是Python中的一个锁和密钥函数的简单实现：

class Lock:
               def __init__(self, key_code):
     self.key_code = key_code
          self.is_locked = True

          def lock(self):
    self.is_locked = True

def unlock(self, entered_code):
    if entered_code == self.key_code:
        self.is_locked = False
    else:
        print("Incorrect key code. Lock remains locked.")

def is_locked(self):
    return self.is_locked

        def main():
key_code = input("Enter the desired key code: ")
my_lock = Lock(key_code)

print("The lock is currently locked.")
while my_lock.is_locked():
    entered_code = input("Enter the key code: ")
    my_lock.unlock(entered_code)

print("The lock is now unlocked.")

        if __name__ == "__main__":
        main()

当您运行代码时，它将遵循以下步骤：
1系统提示用户输入所需的键码。2使用输入的键代码创建Lock类的示例。3程序通知用户锁当前已锁定。4它运行一个循环，不断要求用户输入钥匙代码，直到提供正确的钥匙代码，锁被解锁。6输入正确的钥匙密码后，循环中断，并打印消息“The lock is 7 now unlocked.（锁已解锁）”。

你几乎在那里：你的代码中有一个小错误。构造函数方法应该命名为init（带双下划线），而不是init。ii.你有一个名为is_locked的示例变量和一个名为is_locked的方法。这可能导致冲突。我将该方法重命名为is_locked_status以避免冲突。iii.调用is_locked_status方法时，需要使用圆括号（）来调用该方法并获取其返回值。

class Lock:
    def __init__(self):  # Use double underscores for the constructor method name
        self.key_code = "1234"
        self.is_locked = True

    def lock(self):
        self.is_locked = True

    def unlock(self, entered_code):
        if entered_code == self.key_code:
            self.is_locked = False
        else:
            print("Incorrect key code. Lock remains locked.")

    def is_locked_status(self):  # Rename the method to avoid name conflict
        return self.is_locked

def main():
    my_lock = Lock()

    print("The lock is currently locked.")
    while my_lock.is_locked_status():  # Call the renamed method
        entered_code = input("Enter the key code: ")
        my_lock.unlock(entered_code)
    print("The lock is now unlocked.")

if __name__ == "__main__":

这里有两种方法来做到这一点。

class Lock:

    def __init__(self):
        self.key_code = "1234"  # Change this to your desired key code
        self.is_locked = True

    def lock(self):
        self.is_locked = True

    def unlock(self, entered_code):
        if entered_code == self.key_code:
            self.is_locked = False
        else:
            print("Incorrect key code. Lock remains locked.")

    def is_locked(self):
        return self.is_locked

def main():
    my_lock = Lock()

    print("The lock is currently locked.")
    while my_lock.is_locked:  # <-- Use variable here instead of getter
        entered_code = input("Enter the key code: ")
        my_lock.unlock(entered_code)

    print("The lock is now unlocked.")

if __name__ == "__main__":

这是可行的，但是你想使用getter来访问你的变量。

class Lock:

    def __init__(self):
        self.key_code = "1234"  # Change this to your desired key code
        self.locked = True

    def lock(self):
        self.locked = True

    def unlock(self, entered_code):
        if entered_code == self.key_code:
            self.locked = False
        else:
            print("Incorrect key code. Lock remains locked.")

    def is_locked(self):
        return self.locked

def main():
    my_lock = Lock()

    print("The lock is currently locked.")
    while my_lock.is_locked():
        entered_code = input("Enter the key code: ")
        my_lock.unlock(entered_code)

    print("The lock is now unlocked.")

if __name__ == "__main__":

问题是变量和方法具有相同的名称。提示在错误中-它使用的变量认为它是一个方法，而不是使用同名的方法。将变量更改为locked使其工作。

class Lock:
def __init__(self):
    self.passcode_file = "passcode.txt"
    self.key_code = self.load_passcode()
    self.is_locked = True

def load_passcode(self):
    try:
        with open(self.passcode_file, "r") as file:
            return file.read().strip()
    except FileNotFoundError:
        return None

def set_passcode(self, new_passcode):
    self.key_code = new_passcode
    with open(self.passcode_file, "w") as file:
        file.write(new_passcode)

def lock(self):
    self.is_locked = True

def unlock(self, entered_code):
    if entered_code == self.key_code:
        self.is_locked = False
    else:
        print("Incorrect passcode. Lock remains locked.")

def get_lock_status(self):

    new_passcode = input("Set up your passcode: ")

    print("Passcode set successfully!")

print("The lock is currently locked.")
while my_lock.get_lock_status():

试试这个代码

这个问题是由于is_locked属性和is_locked（）方法之间的命名冲突造成的。两者具有相同的名称，这导致了错误。为了解决这个问题，让我们将方法重命名为get_lock_status（）而不是is_locked（）。下面是更正的代码：
class Lock：definit（self）：self.key_code =“1234”
self.is_locked = True

def lock(self):
             self.is_locked  = True

def unlock(self, entered_code):
    if entered_code == self.key_code:
        self.is_locked = False
    else:
        print("Incorrect key code. Lock remains locked.")

def get_lock_status(self):
    return self.is_locked

        def main():
               my_lock = Lock()

print("The lock is currently locked.")
while my_lock.get_lock_status():
    entered_code = input("Enter the key code: ")
    my_lock.unlock(entered code)

print("The lock is now unlocked.")
    if __name__ == "__main__":
