Chapter 10. Working with Threads in Python

In Chapter 08, Advanced Introduction to Concurrent and Parallel Programming, you saw an example of threads being used in concurrent and parallel programming. In this chapter, you will be introduced to the formal definition of a thread, as well as the threading module in Python. We will cover a number of ways to work with threads in a Python program, including activities such as creating new threads, synchronizing threads, and working with multithreaded priority queues, via specific examples. We will also discuss the concept of a lock in thread synchronization, and we will implement a lock-based multithreaded application, in order to better understand the benefits of thread synchronization.

The following topics will be covered in this chapter:

• The concept of a thread in the context of concurrent programming in computer science
• The basic API of the threading module in Python
• How to create a new thread via the threading module
• The concept of a lock and...
