This also includes Fred's updates to the `README-short.txt` files, and a bunch of very minor changes for consistency (using "PHP" instead of "php", ending sentences that describe and lead into a code block with a ":", using "Go" instead of "Golang" and "Hy" instead of "Hylang" within prose, not using periods at the end of headlines, etc). A really fun one included here is that Java mentioned both using GNU Make inside the container (and `java` doesn't include `make` presently), and some of the prose mentioned `go build` after we ran `javac`, which was extra neat.

What is Python?
Python is an interpreted, interactive, object-oriented, open-source programming language. It incorporates modules, exceptions, dynamic typing, very high level dynamic data types, and classes. Python combines remarkable power with very clear syntax. It has interfaces to many system calls and libraries, as well as to various window systems, and is extensible in C or C++. It is also usable as an extension language for applications that need a programmable interface. Finally, Python is portable: it runs on many Unix variants, on the Mac, and on Windows 2000 and later.
How to use this image
Create a Dockerfile in your Python app project
FROM python:3
COPY . /usr/src/myapp
WORKDIR /usr/src/myapp
CMD [ "python", "./your-daemon-or-script.py" ]
or (if you need to use Python 2):
FROM python:2
COPY . /usr/src/myapp
WORKDIR /usr/src/myapp
CMD [ "python", "./your-daemon-or-script.py" ]
You can then build and run the Docker image:
docker build -t my-python-app
docker run -it --rm --name my-running-app my-python-app
Run a single Python script
For many simple, single file projects, you may find it inconvenient to write a
complete Dockerfile. In such cases, you can run a Python script by using the
Python Docker image directly:
docker run -it --rm --name my-running-script -v "$(pwd)":/usr/src/myapp -w /usr/src/myapp python:3 python your-daemon-or-script.py
or (again, if you need to use Python 2):
docker run -it --rm --name my-running-script -v "$(pwd)":/usr/src/myapp -w /usr/src/myapp python:2 python your-daemon-or-script.py
