Answer all questions and submit to see your results.</p> <p>Before diving into the MCQ, let&rsquo;s briefly touch upon a few key advanced theoretical concepts that often underpin questions about libraries and system design.</p> <h3 id="q1-explain-the-python-global-interpreter-lock-gil-and-its-implications-for-multi-threaded-applications">Q1: Explain the Python Global Interpreter Lock (GIL) and its implications for multi-threaded applications.</h3> <p><strong>A:</strong> The Global Interpreter Lock (GIL) is a mutex (mutual exclusion lock) that protects access to Python objects, preventing multiple native threads from executing Python bytecodes simultaneously. This means that even on multi-core processors, only one thread can execute Python bytecode at any given time, effectively turning CPU-bound multi-threaded Python programs into single-threaded ones in terms of actual CPU utilization for Python code.</p>
