Starvation: Python demo
- [Instructor] To demonstrate thread starvation in Python, we'll modify the dining philosopher's example by adding a local variable within the philosopher function to keep track of how many pieces of sushi each philosopher thread gets to eat. I'm going to name that sushi_eaten, and I'll initialize it to zero. We'll increment the sushi eaten variable every time the philosopher takes a piece of sushi. Sushi_eaten plus equals one. And at the end of the philosopher function, after the while loop has finished, we'll print out the number of pieces that it took. Print(name, 'took' sushi_eaten, 'pieces'). There are currently 5,000 pieces of sushi up for grabs on line nine, so I'll switch over to a command prompt and run this program. When it finishes, we see that each of the three philosophers got a different amount of sushi, and it's not particularly fair. Olivia took way more sushi than Barron or Steve. She has over 3,000 of the pieces. But it's not because she's greedy. In this case, it's…
