This document provides an overview of Python programming. It begins with an introduction to programming languages in general, explaining that they consist of rules and syntax for telling computers what operations to perform. It then discusses why Python is a popular language, noting that it is open source, portable, easy to learn, requires no compilation, and has powerful libraries. The document provides instructions for installing Python and describes different ways to use it interactively or by writing files. It also covers Python variables and data types, naming conventions, basic operators, string and list methods, printing, and comments. The goal is to introduce fundamental Python concepts.

10. Why there are so many languages

11. Why there are so many languages
• Different tools for 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

1-Write directly to the python Shell
2-Write files.py then execute it
FILE  New file  Write your Code
save the file .py ie “TEST.py”
Then run

35. Variables and Types
Integers
All Numbers except
fractions

36. Variables and Types
Integers Float
All Numbers except
fractions
Fractional numbers

37. Variables and Types
Integers Float Characters
All Numbers except
fractions
Fractional numbers Including ‘A’ :’Z’
Alphabetic ‘@’,’&’

38. Variables and Types
Integers Float Characters Strings
All Numbers except
fractions
Fractional numbers Including ‘A’ :’Z’
Alphabetic ‘@’,’&’
Like any names

39. More types
None
It’s a way if saying NULL in python
That evaluates to False

40. More types
None Boolean
It’s a way if saying NULL in python
That evaluates to False

42. How to name variables!
• Must start with a latter or an underscore
 Name or _Name
• Don’t Start with Numbers
 8name = “Mohamed”
• Names are case sensitive
 Name name NAME are diffirent

44. Operators

45. Practice
Add/Subtract/Multiply/divide/get modules/Quotient/Power

46. Operations
• Note :-
When dividing two integers
In Python 2.2 or later there’s no difference between ‘/’ and ‘//’
7 //2 = 2 Neglect the fraction part
5/2 = 2 Also Neglect the fraction part !
Then how to solve?
By importing library called division in this way
From __future__ import division
Or
you can use 5/2. = 2.5 that mean divide integer over float

47. Operators

48. Practice
Compare between two values
