Code examples from my toptal engineering blog article

Python concurrency

This is the code used as examples in the post that I wrote for the Toptal Engineering Blog.

Running the examples

The examples have all been tested under Python 3.6.4 running on OS X. They should work on other operating systems and Python 3.5+, but I haven't tested it everywhere.

1. Get an Imgur API Key
2. Install dependencies with pip install -r requirements.txt
3. Run an example IMGUR_CLIENT_ID=your_client_id threading_imgur.py
   1. For the rq_imgur.py example you will also need to be running a redis server

python-concurrency's Issues

how "redis" help's python-concurrency? and other requirements too?

Help me to understand.
I couldn't get , is any advantages are there to install requirements.txt file?
aiohttp==0.14.4
click==3.3
greenlet==0.4.5
redis==2.10.3
rq==0.5.0

Thank you.

threading_imgur has a bug

Exception in thread Thread-7:

It seems image.read() incured.
