This document examines concurrency and parallelism as fundamental techniques for optimizing Python applications. It distinguishes between concurrency for I/O-bound tasks using threading and asyncio, parallelism for CPU-bound tasks using multiprocessing, and strategies for combining both approaches to create high-performance applications that efficiently manage both computational workloads and external resource dependencies.
&lt;/p&gt;

&lt;p&gt;In Python, concurrency can be used to allow multiple tasks to make progress at the same time, even if they don&amp;rsquo;t actually run simultaneously. This is useful when optimizing how tasks are scheduled and resources are used, especially for I/O-bound tasks.&lt;/p&gt;</description></item></channel></rss>
