how to tell if a semaphore is full in python
python, semaphore
Solution
A pool of workers sounds like a good solution for this, so you might consider this question and its answers. You can create the pool of workers, submit all the jobs, `close` the pool, and then `join` it to wait for things to finish before handing off to the code you want to run when the files are done downloading.
Problem
I have a bounded semaphore object that ensures my program doesn't download more than a certain number of files at a time. Each worker thread acquires the semaphore when it starts downloading and releases it when done. I have another thread that would like to run code when nothing is being downloaded. I would like a method for locking until the semaphore is completely available. How can I do this in Python?
