What is thread priority in Python threading?

Thread priority in Python threading refers to the importance assigned to a thread’s execution relative to other threads. Higher-priority threads may be given preference by the scheduler, though in Python, the Global Interpreter Lock (GIL) often limits the effectiveness of thread priorities.

Python does not provide direct control over thread priorities through the threading module. However, you can simulate priority by managing the execution order and timing of threads using techniques such as time.sleep() to delay lower-priority threads or by structuring your code to prioritize certain threads.

While thread priority is a key concept in some languages and systems, Python’s threading relies more on cooperative multitasking due to the GIL, so thread priority is less impactful in typical Python applications.
