Global Interpreter Lock (GIL) | Python Interview QNA Shorts - 01|
Global Interpreter Lock (GIL)
In Python, when multiple threads are executing the same operation, the Global Interpreter Lock (GIL) allows only one thread to access the interpreter and locks the environment until the thread completes its execution. Afterward, the lock is released, allowing another thread to acquire it and proceed. This sequential locking ensures that only one thread executes Python bytecode at any given time, impacting the parallelism of multithreaded programs.
