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 = re.search(pat, str) The re.search() 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 = re.search(pat, 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)?
“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 bugs.winehq.org 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.

The importance of coding lies in the fact that it enables students to learn a slew of other important skills all along the way. In his popular TED talk " Let's Teach Kids to Code", Mitch Resnick of MIT Media Lab outlined a set of skills that students get to learn from coding . These skills are also relevant for all other sorts of activities: Code Racer that is featured in TED article has become Treehouse which brings the number of websites to 9. 1- Code Academy This by far the most popular of them all. 2- Girl Develop It One of many programs geared toward females who want to code, Girl Develop It is an international nonprofit that provides mentorship and instruction. 3- Udacity Computer Science Course ( not free) Stanford University’s Udacity is one of many sites that make college courses—including Introduction to Computer Science—available online for free.
