This course offers an in-depth exploration of the creation and management of concurrent threads in Python. In its 14 videos, you will learn how to significantly improve the performance and responsiveness of your apps by using concurrent threads. Begin by examining how threads are created in Python from their initialization to their execution; then learn how to use the various synchronization mechanisms such as locks, semaphores, and events. Next, you will examine how concurrent execution could occur in two ways: multithreading and parallel. You will learn to use multithreading to run chunks of each task at one time, and then switch between them regularly. You will learn multiprocessing of threads by executing tasks in parallel. Learners will examine concurrent execution of threads, and some of the issues that arise when these threads are not synchronized. Finally, you will examine several threads of synchronization mechanisms available in Python such as locks, semaphores, events, and conditions and explore the properties and use cases for each of these objects.

WHAT YOU WILL LEARN

  • Discover the key concepts covered in this course
    Initialize and execute a thread in python
    Set a name for a thread and ensure a thread waits for a created thread to complete
    Define your own type to run in a thread by deriving the multithreading.thread class
    Execute two threads concurrently to save time relative to a sequential execution
    Identify what a race condition is and when this may occur with multithreading
    Use a lock to synchronize threads that update a shared resource
  • Recognize the conditions under which a deadlock may occur
    Define tasks in such a manner that deadlocks will not occur
    Create semaphores in python and recognize the effect of calling their acquire and release methods
    Describe the use of boundedsemaphores to restrict the number of times a semaphore can be released
    Define threads that will wait for an event to occur before they can proceed
    Create a condition instance that will have multiple threads waiting for data to be generated
    Recall how to retrieve details about running threads and describe semaphores in python
