Python Gevent in practice: common pitfalls to keep in mind

Gevent is a Python networking library offering asynchronous programming capabilities through the use of greenlets and an event loop, providing a less complex alternative to traditional multithreading. The library is inspired by Eventlet and is ideal for high-performance networking applications, allowing for concurrent execution without relying on OS threads. However, developers should be aware of common pitfalls such as the need for monkey patching, which replaces blocking standard library calls with cooperative ones, and its limitations in making third-party libraries asynchronous. Gevent is not well-suited for CPU-intensive tasks, as these can block greenlets from executing, and shared resource access can lead to subtle issues unless carefully managed. While Gevent simplifies asynchronous programming, understanding its limitations and adhering to best practices is crucial for effective use in applications.
