How do I implement read locks in my application?

To implement read locks, you can use a locking mechanism that allows multiple readers but prevents writers. Are you using a specific programming language?

Yes, I'm using Python. Any libraries you recommend?

In Python, you can use the threading module, specifically RLock for reentrant locks. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

import threading

class ReadWriteLock:
    def __init__(self):
        self.read_lock = threading.RLock()
        self.write_lock = threading.Lock()
        self.readers = 0

    def acquire_read(self):
        with self.read_lock:
            self.readers += 1
            if self.readers == 1:
                self.write_lock.acquire()

    def release_read(self):
        with self.read_lock:
            self.readers -= 1
            if self.readers == 0:
                self.write_lock.release()

This allows multiple readers to access the resource simultaneously.
