Agenda• What is the Python ?• Creator• The Zen of Python• Interpreters• Package Management• Cross – Platform• Why Python ?• Disadvantages of Python• Python Frameworks• Commercial Uses• Popularity

What is the Python ?• Open source• Multi-paradigm programming language• High-level programming language• Readability• Automatic memory management• Large and comprehensive standard library• Available many operating systems

Creator• Created by Guidio van Rossum • Start as hobby project• First released in 1991, 1.0

published in 1994• Name came from “Monty

Python” comedy program

The Zen of Python, by Tim Peters• Beautiful is better than ugly.• Explicit is better than implicit.• Simple is better than complex.• Complex is better than complicated.• Flat is better than nested.

http://docs.python-guide.org/en/latest/writing/style/#zen-of-python

Interpreters• CPython: Reference implementation• IronPython: .Net and Mono platforms• Jython: Java platforms• PyPy: Alternative implementation, coded in python (faster in some

cases)• CLPython: Comon Lisp implementation

Package Management• Use pip to install packages from PyPI*• Use virtualenv, or venv to isolate application specific dependencies

from a shared Python installation.• If you’re looking for management of fully integrated cross-platform

software stacks, consider:buildout: primarily focused on the web development communitySpack, Hashdist, or conda: primarily focused on the scientific

community.

*PyPI is the default package index for the Python community. It is open to all Python developers to consume and distribute their distributions.

Cross - Platform

Why Python ?• Open Source• Readability• Easy learn• Interpreter language• Functional language• Object Oriented Programming - driven• Large scientific library

Why Python ?• Embeddable other language• Fast write• Virtual environment• Package management• Automatic memory management• Easy to refactor• With the introduction of Raspberry Pi• Gives rise to quick development by using less code.

Disadvantages of Python• Python is slow• Python is not a very good language for mobile development• Python is not a good choice for memory intensive tasks• Has limitations with database access• Python is not good for multi-processor/multi-core work

Python Frameworks• Django• Pyramid• Flask• Tornado• Google App Engine

• Tkinder• wxPython• PyQt
