- [Instructor] To demonstrate thread starvation in Python we'll modify the dining philosophers 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 += 1, and at the end of the philosopher function after the while loop had finished we'll print out the number of pieces that it took. print(name), 'took', sushi_eaten, 'pieces' There are currently 5000 pieces of sushi up for grabs on line 9, so I'll switch over to a command prompt and run this program. (keys clacking) 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 3000 of the…
