Python Regular Expressions - Educational Materials

This page gives a basic introduction to regular expressions themselves sufficient for our Python exercises and shows how regular expressions work in Python. The Python "re" module provides regular expression support. In Python a regular expression search is typically written as: match =, str) The method takes a regular expression pattern and a string and searches for that pattern within the string. Str = 'an example word:cat!! ' The code match =, str) stores the search result in a variable named "match". The 'r' at the start of the pattern string designates a python "raw" string which passes through backslashes without change which is very handy for regular expressions (Java needs this feature badly!).

Basic Patterns The power of regular expressions is that they can specify patterns, not just fixed characters. A, X, 9, < -- ordinary characters just match themselves exactly. Findall. VLAN Trunking Protocol (VTP) & VTP Modes » Router Switch Blog. What is a VLAN Trunking Protocol (VTP)?

VLAN Trunking Protocol (VTP) & VTP Modes » Router Switch Blog

“VTP allows a network manager to configure a switch so that it will propagate VLAN configurations to other switches in the network” VLAN Trunking Protocol (VTP) is a Cisco proprietary Layer 2 messaging protocol that manages the addition, deletion, and renaming of VLANs for the Cisco Catalyst Switches in the same VLAN Trunking Protocol (VTP) domain. VLAN Trunking Protocol (VTP) enables Cisco Catalyst Switches to exchange and maintain consistent VLAN information amongst a group of Cisco Catalyst Switches.

For example, information for the VLAN 50 defined in Cisco Catalyst Switch A is propagated via VTP updates to all other Cisco Catalyst Switches (Switches B, C and D) in the same VTP domain, the other Cisco Catalyst Switches B, C and D will all end up adding VLAN 50 in their local VLAN data base. VTP is available on most of the Cisco Catalyst Family products. The comparable IEEE standard in use by other manufacturers is GVRP. GoogleSketchup. Sketchup is a freely downloadable 3D modeling application first introduced for MS Windows in 2000.


As of Wine-1.0, Sketchup 6 and 7 both run on Wine, at least with Nvidia graphics cards, although you may have to jump through some hoops to get it working. If you've been waiting to run Sketchup in Linux, wait no more! Please test it against wine-1.1.11 or later, and file bugs at for any new problems you find. Tips: bug 14045; fixed as of wine-1.3.18: If you get the error "SketchUp was unable to initialize OpenGL!] Coding. 18 Hot IT Certifications for 2014.
