Create a simple lock and key function in Python

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():
        entered code = input("Enter the key code: ")
        my_lock.unlock(entered code)

    print("The lock is now unlocked.")


if __name__ == "__main__":
    main()

I wrote this code but it is showing an

Type Error: 'bool' object is not callable
The lock is currently locked.

I have been trying to create a lock mechanism but it is showing an type error. I had tried many ways but I still couldn’t solve it.

>Solution :

he issue is due to the naming conflict between the is_locked attribute and the is_locked() method. Both have the same name, and that’s causing the error. To fix it, let’s rename the method to get_lock_status() instead of is_locked(). Here’s the corrected code:

class Lock:
def init(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__":
      main()
