SciPy. Matplotlib. Pandas. Python3-Tutorial: Tutorial für Anfänger und Fortgeschrittene. Für Anfängerinnen und Anfänger stellt sich häufig die Frage, mit welcher Python-Version man anfangen soll, d.h. eine Version 2.x (aktuell, Stand Februar 2014: 2.7.4) oder eine 3.x (aktuell, Stand Februar 2014: 3.34).
Wenn man die Wahl hat, sollte man auf jeden Fall mit Python 3 beginnen, denn dieser gehört die Zukunft. Wir bieten Ihnen hier ein vollständiges Tutorial, was sich als schneller Einstieg mit vielen praktischen Beispielen und erläuternden Illustrationen bestens für Anfänger - sowohl totale Programmieranfänger als auch Umsteiger von anderen Programmiersprachen - eignet. Aber auch fortgeschrittene Programmierer finden sicherlich noch viele interessante Themen und Einblicke.
Nach dem Durcharbeiten der einzelnen Kapitel sollte man in der Lage sein, selbständig Programme zu schreiben und Module zu verwenden. News Mithilfe erwünscht Niemand und nichts ist perfekt.

It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms. The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the Python Web site, and may be freely distributed. The same site also contains distributions of and pointers to many free third party Python modules, programs and tools, and additional documentation.
The Python interpreter is easily extended with new functions and data types implemented in C or C++ (or other languages callable from C). This tutorial introduces the reader informally to the basic concepts and features of the Python language and system. The Glossary is also worth going through. Python Variable Types. Variables are nothing but reserved memory locations to store values.
This means that when you create a variable you reserve some space in memory. Based on the data type of a variable, the interpreter allocates memory and decides what can be stored in the reserved memory. Therefore, by assigning different data types to variables, you can store integers, decimals or characters in these variables.
Assigning Values to Variables Python variables do not need explicit declaration to reserve memory space. The operand to the left of the = operator is the name of the variable and the operand to the right of the = operator is the value stored in the variable. Live Demo #!
