queue | Python Standard Library – Real Python
The Python queue module provides reliable thread-safe implementations of the queue data structure. It is commonly used for task scheduling and managing work between multiple threads.
Here’s a quick example:
Key Features
- Provides thread-safe FIFO, LIFO, and priority queues
- Supports blocking and non-blocking operations
- Allows a maximum size to be set for queues
Frequently Used Classes and Functions
Examples
Using a LIFO queue:
Using a priority queue:
Common Use Cases
- Managing task scheduling in multi-threaded applications
- Implementing producer-consumer patterns
- Prioritizing tasks using priority queues
Real-World Example
Consider a scenario where multiple worker threads need to process tasks concurrently. In this situation, you can use the queue module to manage these tasks efficiently:
In this example, you use the queue module to distribute tasks among two worker threads, ensuring that each task is processed exactly once.
