Queue Exercise Hint

Did you get your code working? The exercise may feel challenging at first because the context is new. Let’s try to organize our thoughts a bit with some pseudocode:

'''
def greet2():
    for 5 times
        get name from queue
        say hello

def sendName2():
    queue
    make a child process, give it the queue
    start it

    for 5 times
        sleep for a bit
        put another name in the queue
'''

When we work in psuedocode, it frees us from having to think about new syntax and other details all at once. Instead we’re free to get some big picture ideas down first. In the above psuedocode you can see that the parent process, in sendName2, will make a queue and a child process. It will then loop five times, sending one piece of data at a time to the child via the queue. The child, in greet2, will also loop five times, getting something from the queue and printing. Recall that if the child attempts to get something from the queue when there’s nothing there, it will block until something is available to get. If you didn’t already solve this problem, try again now, using the pseudocode as a guide.

With this pseudocode developed, the actual code comes much more easily.
