How do I implement shared locks in my application?

To implement shared locks, you can use a locking mechanism that allows multiple readers but only one writer. Are you using a specific programming language?

Yes, I'm using Python. Can you provide a code example?

Sure! You can use the threading module. Here's a simple example:

import threading

class SharedResource:
    def __init__(self):
        self.lock = threading.RLock()
        self.data = []

    def read(self):
        with self.lock:
            return self.data

    def write(self, value):
        with self.lock:
            self.data.append(value)

What if I want to allow multiple writers?

If you want to allow multiple writers, you might need to implement a different locking strategy, like using a write lock that blocks readers. Would you like to explore that?
