+
+## Description
+
+[Python](https://www.python.org/) is an interpreted, interactive, object-oriented, open-source programming language. It incorporates modules, exceptions, dynamic typing, high-level dynamic data types, and classes. It provides interfaces to many system calls, libraries, and various window systems, and it is extensible in C or C++. It is also usable as an extension language for applications that require programmable interfaces.
+
+## Usage
+
+To deploy an application, install dependencies, copy the sources, and configure the application's main script:
+
+```Dockerfile
+FROM {{ image.pretty_reference }}
+
+WORKDIR /app
+
+COPY requirements.txt ./
+RUN pip install --no-cache-dir -r requirements.txt
+
+COPY . .
+
+CMD [ "python", "./main-script.py" ]
+```
+
+Build and run the container image:
+
+```ShellSession
+$ podman build -t my-python-app .
+$ podman run -it --rm my-python-app
+```
+
+To run a single script inside a container, use the following command:
+
+```ShellSession
+$ podman run --rm -v "$PWD":/app:Z -w /app {{ image.pretty_reference }} python3 script.py
+```
+
