Static variables in Python are created as part of the class declaration. By contrast, instance variables are created as part of a regular method and not a classmethod or staticmethod.
class A:
i=3 # static variable
def dosomethingregularmethod(self):
self.k=4 # instance variable
# to access static variables

As developers we are overwhelmed with the number of language choices made available to us. It wasn't so long ago that C and it's object oriented sibling C++ where the mainstay of any programmer. Now though we have languages which make certain tasks so easy and simple that we simply cannot afford to ignore them.
In this article we are going to look at the overall differences between Python, Perl and TCL. All formidable and worthy in their own right, but each one has been designed to suit a specific programming need.
1)– Perl is the most mature out of the three languages we are looking at in this article. It was originally designed for processing textual data, and it does so extremely well. Of course Perl has grown over time and can be used for a multitude of different programming scenarios.
Straight up and full disclosure. I'm prejudiced. As a research assignment, the heading is a joke. I'll give you the answer in two words, and then tell you why.
How does HTML 5 compare with flash? Answer: it doesn't.
Lest you think I dislike Adobe's Flash, let's put the cards on the table. I loved Flash. Long before Adobe was Adobe, they had a competitor called Macromedia. Adobe bought that firm. That made my life simpler. I only had to work with one vendor.
Flash was a pretty compelling solution. I used it to mimic operations in Windows to prepare people for the CompTIA exams. The only bugaboo was that dang right-click stuff. A little bit of code from the Microsoft Visual Studio .Net let me flip the left and right mouse buttons so that the right mouse button instead of controlling the Flash player, emulated doing a right-click in the Windows operating system.

Recently, I asked my friend, Ray, to list those he believes are the top 10 most forward thinkers in the IT industry. Below is the list he generated.
Like most smart people, Ray gets his information from institutions such as the New York Times, the Wall Street Journal, the Huffington Post, Ted Talks ... Ray is not an IT expert; he is, however, a marketer: the type that has an opinion on everything and is all too willing to share it. Unfortunately, many of his opinions are based upon the writings/editorials of those attempting to appeal to the reading level of an 8th grader. I suppose it could be worse. He could be referencing Yahoo News, where important stories get priority placement such as when the voluptuous Kate Upton holds a computer close to her breasts.
Before you read further, note that missing from this list and not credited are innovators: Bill Joy, Dennis Ritchie, Linus Torvalds, Alan Turing, Edward Howard Armstrong, Peter Andreas Grunberg and Albert Fent, Gottfried Wilhelm Leibniz/Hermann Grassmann ... You know the type: the type of individual who burns the midnight oil and rarely, if ever, guffaws over their discoveries or achievements.
