Python

In Greek mythology, Python is the name of a a huge serpent and sometimes a dragon. Python had been killed by the god Apollo at Delphi. Python was created out of the slime and mud left after the great flood. He was appointed by Gaia (Mother Earth) to guard the oracle of Delphi, known as Pytho.
The programming language Python has not been created out of slime and mud but out of the programming language ABC. It has been devised by a Dutch programmer, named Guido van Rossum, in Amsterdam.

Origins of Python

Guido van Rossum wrote the following about the origins of Python in a foreword for the book "Programming Python" by Mark Lutz in 1996:
"Over six years ago, in December 1989, I was looking for a "hobby" programming project that would keep me occupied during the week around Christmas. My office (a government-run research lab in Amsterdam) would be closed, but I had a home computer, and not much else on my hands. I decided to write an interpreter for the new scripting language I had been thinking about lately: a descendant of ABC that would appeal to Unix/C hackers. I chose Python as a working title for the project, being in a slightly irreverent mood (and a big fan of Monty Python's Flying Circus)."

Quote of the Day:

"Language designers want to design the perfect language. They want to be able to say, "My language is perfect. It can do everything." But it's just plain impossible to design a perfect language, because there are two ways to look at a language. One way is by looking at what can be done with that language. The other is by looking at how we feel using that language - how we feel while programming." (-Yukihiro 'Matz' Matsumoto)

If you have the choice working with Python 2 or Python 3, we recomend to switch to Python 3! You can read our Python Tutorial to see what the differences are.

Data Protection Declaration

Python-Modul pygraph

This chapter is still not finished. We are working on it. This software provides a suitable data structure for representing graphs and a whole set of important algorithms. Provided features and algorithms:

• Support for directed, undirected, weighted and non-weighted graphs
• Support for hypergraphs
• Canonical operations
• XML import and export
• DOT-Language output (for usage with Graphviz)
• Random graph generation
• Accessibility (transitive closure)
• Breadth-first search
• Critical path algorithm
• Cut-vertex and cut-edge identification
• Cycle detection
• Depth-first search
• Heuristic search (A* algorithm)
• Identification of connected components
• Minimum spanning tree (Prim's algorithm)
• Mutual-accessibility (strongly connected components)
• Shortest path search (Dijkstra's algorithm)
• Topological sorting
• Transitive edge identification

Python-Modul pygraphviz

With Pygraphviz you can create, edit, read, write, and draw graphs using Python to access the Graphviz graph data structure and layout algorithms.
