<\/p>\nPicture a kitchen in India with two cooks, Gautam and Badal. They\u2019re both preparing delicious dishes, but there\u2019s a unique spice box they both want to use. However, only one cook can use it at a time.<\/p>\n
<\/p>\n
Here\u2019s how they ensure a flavorful collaboration:<\/p>\n
Diverse Tasks:<\/strong><\/p>\n Single Spice Box:<\/strong><\/p>\n Alternating Turns:<\/strong><\/p>\n Effective Communication:<\/strong><\/p>\n Harmonious Cooking:<\/strong><\/p>\n <\/p>\n This scenario mirrors thread synchronization in the programming world, particularly with threads. Threads<\/a>, like Gautam and Badal, work together, taking turns to access shared resources and ensuring a harmonious process.<\/em><\/p>\n Let\u2019s talk about how threads can play nicely together in Python. It\u2019s like teaching them to take turns to work together without causing a mess.<\/p>\n Basic knowledge of\u00a0multi-threading<\/a> will make you a quick learner. <\/em>In Python, there\u2019s a cool module called\u00a0 The threading module in Python has four special classes that help your threads play fair and take turns. It\u2019s like having rules to ensure everyone gets a chance to do their job without any chaos.<\/p>\n Lock<\/strong><\/p>\n It is like a key that threads use to access a shared resource one at a time. It prevents conflicts by allowing only one Thread to hold the lock, ensuring the orderly execution of critical code sections.<\/p>\n Let\u2019s say Gautam is using a knife to chop something so Badal has to wait till Gautam releases the knife.<\/em><\/p>\n \u201cLock<\/strong>\u201d allows only one thread to acquire the lock at a time.<\/em><\/p>\n If a thread holds the lock and tries to acquire it again (nested acquisition), it will be deadlocked. In other words, it doesn\u2019t allow the same thread to acquire the lock multiple times. <\/em>It\u2019s simple and suitable for basic synchronization needs.<\/em><\/p>\n RLock (Re-entrant\/Recursive Lock)<\/strong><\/p>\n It is much like\u00a0 The following code will create\u00a0 To overcome this\u00a0 The\u00a0 Semaphore is used to limit the number of threads that can access a resource at the same time. Works same as\u00a0 \n Summary<\/strong><\/p>\n The Lock, RLock, and Semaphore classes enable you to make multiple threads operate on the same resource more efficiently. All three classes control the behavior of a thread over resources and can save you from inconsistency.<\/p>\n Official Website<\/strong>\u00a0https:\/\/pythonbricks.pythonanywhere.com\/<\/a>\n
