This article describes solutions to create a single executable file containing a Python application/script and the Python interpreter DLL with all necessary libraries. The executable file can then be launched on any system even if Python is not installed.

CherryProxy is a simple HTTP proxy written in Python 2.x, based on the CherryPy WSGI server and httplib, extensible for content analysis and filtering.

This article lists solutions to create network servers in Python for different standard protocols: HTTP, FTP, SMTP, SOAP, syslog, WebDAV, ...

ExeFilter is an open-source tool and python framework to filter file formats in e-mails, web pages or files. It detects many common file formats and can remove active content (scripts, macros, etc) according to a configurable policy.

tempfilemgr is a Python 2.x module to easily create temporary files and directories, and to make sure that all of them are deleted after use. It adds several useful features to the standard tempfile module.

Origapy is a Python interface to Origami, a PDF parser written in Ruby. It provides access to pdfclean.rb, in order to sanitize PDF files by disabling all active content (javascript, launch actions, embedded files, etc). Because Origami is a full PDF parser, it is much more effective than PDFiD (when sanitizing/disarming PDF files), but also quite slower.

PDF files may be used to trigger malicious content, as described here. PDFiD is a Python tool to analyze and sanitize PDF files, written by Didier Stevens. Here is PDFiD_PL, a version that I have slightly modified so that it can be imported as a module in Python applications (originally for ExeFilter).

pyxmldsig is a Python module to create and verify XML Digital Signatures (XML-DSig). This is a simple interface to the PyXMLSec library, aiming to provide a more pythonic API suitable for Python applications.

With Python 2.6+, that's quite simple:

print "{0:b}".format(i)

This is a Python course I have written to quickly teach Python to my colleagues and students, made of slides and samples for hands-on exercises.
