Thread priority involves assigning importance levels to different threads within an application, allowing higher priority threads to receive more CPU time compared to lower priority ones.

However, it's crucial to note that Python's standard threading model doesn't support native thread prioritization due to the Global Interpreter Lock (GIL). The GIL ensures that only one thread executes Python bytecode at a time, which simplifies memory management but limits the ability to directly manipulate thread priorities like in other programming environments
