  1. PYTHON WHAT IS PYTHON? Pythonis an interpreted high-level programming language for general-purpose programming. Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace. Python interpreters are available for many operating systems.

  2. PYTHON FEATURES • Easy-to-learn − Python has few keywords, simple structure, and a clearly defined syntax. This allows the student to pick up the language quickly. • Easy-to-read − Python code is more clearly defined and visible to the eyes. • Easy-to-maintain − Python's source code is fairly easy-to-maintain. • A broad standard library − Python's bulk of the library is very portable and cross-platform compatible on UNIX, Windows, and Macintosh. • Interactive Mode − Python has support for an interactive mode which allows interactive testing and debugging of snippets of code. • Portable − Python can run on a wide variety of hardware platforms and has the same interface on all platforms.

  3. It supports functional and structured programming methods as well as OOP. It can be used as a scripting language or can be compiled to byte-code for building large applications. It provides very high-level dynamic data types and supports dynamic type checking. IT supports automatic garbage collection. It can be easily integrated with C, C++, COM, ActiveX, CORBA, and Java.

  4. Types of Operator • Arithmetic Operators • Comparison (Relational) Operators • Assignment Operators • Logical Operators • Bitwise Operators • Membership Operators • Identity Operators

  5. LOOPS WHILE LOOP FOR LOOP NESTED LOOP • Repeats a statement or group of statements while a given condition is TRUE. It tests the condition before executing the loop body. • Executes a sequence of statements multiple times and abbreviates the code that manages the loop variable. • You can use one or more loop inside any another while, for or do..while loop.

  6. PYTHON NUMBERS INT - They are often called just integers or ints, are positive or negative whole numbers with no decimal point. LONG -Also called longs, they are integers of unlimited size, written like integers and followed by an uppercase or lowercase L. FLOAT -Floats may also be in scientific notation, with E or e indicating the power of 10 (2.5e2 = 2.5 x 102 = 250). COMPLEX -The real part of the number is a, and the imaginary part is b. Complex numbers are not used much in Python programming.

  7. PYTHON - LIST The list is a most versatile datatype available in Python which can be written as a list of comma-separated values (items) between square brackets. Important thing about a list is that items in a list need not be of the same type. FOR EXAMPLE, list1 = ['physics', 'chemistry', 1997, 2000]; list2 = [1, 2, 3, 4, 5 ]; list3 = ["a", "b", "c", "d"]

  8. ACCESSING VALUES IN LIST To access values in lists, use the square brackets for slicing along with the index or indices to obtain value available at that index.  FOR EXAMPLE, list1 =['physics','chemistry',1997,2000]; list2 =[1,2,3,4,5,6,7];print"list1[0]: ", list1[0]print"list2[1:5]: ", list2[1:5]

  9. UPDATING LIST You can update single or multiple elements of lists by giving the slice on the left-hand side of the assignment operator, and you can add to elements in a list with the append() method.  FOR EXAMPLE,list =['physics','chemistry',1997,2000];print"Value available at index 2 : "print list[2] list[2]=2001;print"New value available at index 2 : "print list[2]

  10. DELETE LIST To remove a list element, you can use either the del statement if you know exactly which element(s) you are deleting or the remove() method if you do not know. FOR EXAMPLE, list1 =['physics','chemistry',1997,2000];print list1 del list1[2];print"After deleting value at index 2 : "print list1
