The goal of the Python Essential Reference is to concisely describe the Python programming language and its large library of standard modules, collectively known as the Python programming "environment." This informal language reference is arranged into four major parts: a brief tutorial, an introduction to Python; an informal language reference that covers lexical conventions, functions, statements, control flow, datatypes, classes, and execution models; the Python library; and the Python C API used to write Python extensions.

Along with several other popular scripting languages, Python is an excellent tool for scanning and manipulating textual data. This article summarizes Python's text processing facilities for the programmer new to Python. The article explains some general concepts of regular expressions and offers advice on when to use (or not use) regular expressions while processing text.

XML is a fairly simple format. It uses plain Unicode text rather than binary encoding, and all the structures are declared with predictable-looking tags. Nonetheless, there are still enough rules in the XML grammar that a carefully debugged parser is needed to process XML documents -- and every parser imposes its own particular programming style. An alternative is to make XML even simpler. The open-source PYX format is a purely line-oriented format for representing XML documents that allows for much easier processing of XML document contents with common text tools like grep, sed, awk, wc, and the usual UNIX collection.
