Multithreading can be complicated when threads need to share data or resources. Luckily, the threading module provides many synchronization primitives, including semaphores, condition variables, events, and locks.

However, it is considered a best practice to use the queue module. In fact, a queue is much easier to deal with and makes threaded programming considerably safer, as it effectively funnels all access to a resource of a single thread and allows for a cleaner and more readable design pattern.
