All functions to interact with coroutines are avaliable in the coroutine table. A new coroutine is created by using the coroutine.create function with a single argument: a function with the code to be executed: thread1 = coroutine.create(function() print("honk") end)...

Python 2 includes a cmp function which allows you to determine if one object is less than, equal to, or greater than another object. This function can be used to pick a choice out of a list based on one of those three options. Suppose you need to print 'greater than' if x > y, 'less than' if x &...
