- 3. INTRODUCTION TO PROGRAMMINGLANGUAGE • It’s a set of rules that provides a way of telling the computer what operations to performs as it describe computation • English language has words, symbols and grammatical rules • Also programming languages has words and symbols and rule of grammar • The grammatical rules are called Syntax! • Each programming language has it’s own syntax rules.
- 4. WHY THERE ARESO MANY LANGUAGES
- 5. • Different toolsfor different jobs! • Ruby and java script are great job for web sites • C are good in Embedded systems • Objective C used for developing ios applications • C++ used to develop software, videos and games and more WHY THERE ARE SO MANY LANGUAGES
- 6. BRIEF HISTORY • Pythonwas used by thousands of people to do things from testing microchips at Intel, to powering Instagram, to building video games with the Pygame library. • The programming language Python was conceived in the late 1980s. • its implementation was started in December 1989. • It was a successor to the ABC (programming language) capable of exception handling and interfacing with the Amoeba operating system. • February 20, 1991; Python was finally introduced to the public.
- 7. • Python wasderived from a novel entitled Monty Python’s Flying Circus. • Python 2.0 was released on 16 October 2000 and had many major new features, including a cycle-detecting, garbage collector and support for Unicode. • Python 3.0 (initially described as Python 3000 or py3k), is a major, backward-incompatible release that was released after a long period of testing on 3 December 2008. • Python 2.7 BRIEF HISTORY
- 8. DEVELOPER OF PYTHON(PROGRAMMING LANGUAGE) • Guido van Rossum was the creator of Python Programming language. • He was known as a “Benevolent Dictator for Life" (BDFL), meaning that he continues to oversee the Python development process, making decisions where necessary.
- 9. DEVELOPER OF PYTHON(PROGRAMMING LANGUAGE) • He was employed by Google from 2005 until December 7th 2012, where he spent half his time developing the Python language • January 2013, van Rossum started working for Dropbox.
- 10. WHY USE PYTHON?! •Open source & free (Thanks Guidi van Rossum)! • Portable- works on every operating systems • Easy to learn • No compilation necessary. Prototype and run! • Powerful libraries • Used for desktop, web applications ,write GUI interfaces, Mobile app development and embedded system design

- 13. SYNTAX OF PYTHON(PROGRAMMINGLANGUAGE) Comment Syntax
- 14. SYNTAX OF PYTHON(PROGRAMMINGLANGUAGE) Joining two lines Syntax
- 15. SYNTAX OF PYTHON(PROGRAMMINGLANGUAGE) Multiple statements on a single line Syntax
- 16. SYNTAX OF PYTHON(PROGRAMMINGLANGUAGE) Indentation Syntax
- 17. PYTHON’S CODING STYLE •Use 4 spaces per indentation and no tabs. • Do not mix tabs and spaces. Tabs create confusion and it is recommended to use only spaces. • Maximum line length : 79 characters which help users with a small display. • Use blank lines to separate top-level function and class definitions and single blank line to separate methods definitions inside a class and larger blocks of code inside functions. • When possible, put inline comments (should be complete sentences). • Use spaces around expressions and statements.
- 18. WHERE IS PYTHON(PROGRAMMING LANGUAGE) USED • It can be used for web programming (django, Zope, Google App Engine, and much more). • But it also can be used for desktop applications (Blender 3D, or even for games pygame). • Python can also be translated into binary code like java. • Python is simply used for developing sites.
