So why not attend one of the live Python courses in Strasbourg, Paris, Luxembourg, Amsterdam, Zürich / Zurich, Vienna / Wien, London, Berlin, Munich, Hamburg, Frankfurt, Stuttgart, or Lake Constance by Bernd Klein, the author of this tutorial?A regular expression (commonly known as a “regex”) is a string or a sequence of characters that specifies a pattern.Think of it as a search string — but with super powers!The download file available here exemplifies the power of Regular Expression.It uses REG_EXTRACT function to extract first name, middle name and last name from a complete employee name. Download file also contains a detailed Power Point presentation describing functionality and parameters of Regular Expression functions..) Furthermore, if the data is a string type, a string containing only whitespace characters is considered false.If the data is empty, also removes prior errors (such as processing errors) from the field.No meaning save what we choose to impose." (Alan Moore) "Life is like an ever-shifting kaleidoscope - a slight change, and all patterns alter." (Sharon Salzberg) "Some people, when confronted with a problem, think 'I know, I'll use regular expressions.' Now they have two problems." (Jamie Zawinski) "Regular expressions tend to be easier to write than they are to read.This is less of a problem if you are the only one who ever needs to maintain the program (or sed routine, or shell script, or what have you), but if several people need to watch over it, the syntax can turn into more of a hindrance than an aid." (Stephen Ramsay, University of Virginia) This topic in German / Deutsche Übersetzung: Reguläre Ausdrücke This is a tutorial in Python3, but this chapter of our course is available in a version for Python 2.x as well: Regular Expression in Python 2.x The goal of this website is to provide educational material, allowing you to learn Python on your own.provide the foundation for describing or matching data according to defined syntax rules.A regular expression is nothing more than a pattern of characters itself, matched against a certain parcel of text.
