This is a fork of christophetd/docker-python-sandbox.

• To support Docker on Mac, exposed ports on Docker instances (specifically the :3000 port which receives the Python code to be executed) are published on the host machine to a random other port. This library then accesses the container via a URL like "localhost:32456" instead of the container directly such as "127.17.0.1" This fixes an issue where the library would not work on Mac: see this and this for more context.
