Concurrency, Parallelism, and asyncio

Blog post for testdriven.io. If you want to follow along and create the projects yourself, you can find the post here.

Code Examples

Create and activate a new virtual environment:

Windows Powershell, assuming the Python version in your PATH is 3.9+:

PS X:> python -m venv venv
PS X:> .\venv\Scripts\Activate.ps1
(venv) PS X:>

(venv) PS X:> pip install -r requirements.txt

Mac/Linux:

$ python3.9 -m venv venv
$ source venv/bin/activate
(venv)$

(venv)$ pip install -r requirements.txt

Concurrency

(venv)$ python code_examples/concurrency/sync.py
(venv)$ python code_examples/concurrency/threads.py
(venv)$ python code_examples/concurrency/async.py

Parallelism

(venv)$ python code_examples/parallelism/sync.py
(venv)$ python code_examples/parallelism/threads.py
(venv)$ python code_examples/parallelism/multi.py

pytest async

(venv)$ python -m pytest code_examples/pytest_asyncio/test_hello_asyncio.py
(venv)$ python -m pytest code_examples/pytest_asyncio/test_hello_asyncio2.py

asyncio and multiprocessing

(venv)$ python code_examples/asyncio_and_multiprocessing/sync.py
