The concept of deadlock
In the field of computer science, deadlock refers to a specific situation in concurrent programming, in which no progress can be made and the program becomes locked in its current state. In most cases, this phenomenon is caused by a lack of, or mishandled, coordination between different lock objects (for thread synchronization purposes). In this section, we will discuss a thought experiment commonly known as the Dining Philosophers problem, in order to illustrate the concept of deadlock and its causes; from there, you will learn how to simulate the problem in a Python concurrent program.
