Introduction of python programming
- 3. Python introduce in 1989 Java introduce in 1995
- 4. What is python ? It is interpreted. Object Oriented Programming Language. It is Procedural Oriented Programming Language. High level programming with dynamic semantics. Used as a scripting or glue language . Extensive standard library are available in source and can be freely distributed. Ex- Numpy and Pandas etc. It spans multiple platforms, middleware products, and application domains. Create and used third party libraries. Ex. Metaplot for ploting a graph.
- 5. Strengths Program development using Python is 5-10 times faster than using C/C++, and 3-5 times faster than using Java. Object-Oriented nature makes the translation a straightforward process. Also increasing the overall performance, functionality and reliability of the application. (E.g. Case Study: Python in a Commercial Environment, by Greg Stein, Microsoft, in Proceedings of the 6th International Python Conference, and the Alice VR project at UvA and CMU.) Used to implement a web browser (E.g. Grail). Also integrated with the Windows, Linux and MacOS platforms
- 6. Features Free and Open Source Extensible Embeddable Extensive Libraries Run on different operating Systems with some modifications or no modifications. Portable.
- 7. Applications Scientific and Computational Applications. Image Processing and Graphic Design Applications. Games (E.g.- Battlefield 2, Bridge Commander, Civilization IV) Web Frameworks and Web Applications. Operating Systems. Machine Learning and Artificial Intelligence. Data Analysis. Software development. Network Programming. Desktop GUI application.
- 8. Top Companies and organizations used it.
- 9. Python Different Versions Python 1.0 released on October 1996. Python 2.0 released on October 2000. Python 3.0 released on December 2008. Python 3.8.3 released on May 2020.
- 10. Python Compilers • The Python compiler package is a tool for analyzing Python source code and generating Python bytecode. • The compiler contains libraries to generate an abstract syntax tree from Python source code and to generate Python bytecode from the tree. • It can be modified more easily than the built-in compiler.

Editor's Notes
- #3: Interpreted : An interpreted language is a type of programming language for which most of its implementations execute instructions directly and freely line by line , without previously compiling a program into machine-language instructions. Scripting : A script or scripting language is a computer language with a series of commands within a file that is capable of being executed without being compiled. Good examples of server-side scripting languages include Perl, PHP, and Python. The best example of a client side scripting language is JavaScript.

- #7: Slicing : Sometimes, you may not want an entire list or a single item, but a number of items from it. Here, the slicing operator [:] comes into play. Mutable : Mutability is the ability to be mutated, to be changed. A list is mutable, so it is possible to reassign and delete individual items as well.
