- Develop Python Global Interpreter Lock (GIL)
Overview
Python is not the best choice for building highly concurrent, multi-threaded applications, particularly applications with many CPU-bound threads. The main reason for this is Python's Global Interpreter Lock (GIL), a mechanisms that prevents the interpreter from executing more than one instruction at a time, even in the presence of multiple cores.
