Code Examples

Create and activate a new virtual environment:

Windows Powershell, assuming the Python version in your PATH is 3.8:

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

Mac/Linux:

$ python3.8 -m venv venv
$ source venv/bin/activate
(venv)$

Concurrency

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