Python is an open source, multi-paradigm programming language created by Guido van Rossum in 1991. It is high-level, readable, has automatic memory management and a large standard library. Python can be used across many operating systems and for web applications, games, scripting, data science, and more due to its various frameworks and commercial uses. While Python is popular for its readability and ease of use, it does have some disadvantages like being slow for memory intensive tasks.

3. 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

4. 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

5. 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.

6. 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

7. 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 community
Spack, 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.

8. Cross - Platform

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

10. 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.

11. 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

12. Python Frameworks
• Django
• Pyramid
• Flask
• Tornado
• Google App Engine
• Tkinder
• wxPython
• PyQt

13. Commercial Uses
Application Web Application

14. Commercial Uses
