What is Python

• Multi-purpose i.e, Web, Graphical user interface
  (GUI), Scripting and many others.
• Strongly typed as well as dynamically typed.
• Focus on readability as well as productivity.
• Object oriented.
• Interpreted.

3
Characteristics

• Easy to Learn
• High-level Language
• Interactive shell
• Strong introspection
• Cross platform
• Object Oriented
• Everything is an object
• Free and Open Source

4
CONT..

• Useful built-in types (lists, dictionaries)
• Clean syntax, powerful extensions
• Interpreted
• Interactive
• Commonly used for producing HTML content on
  websites. Great for text files
• Functional
• Extensive Libraries

5
Languages

• Few important types
• FORTRAN
• Technology
• COBOL
• Business Information
• LISP
• Logic as well as AI
• BASIC
• Easy Language

6
The Python Interpreter

• Python can be an interpreted terminology
• The actual interpreter has an interactive
  environment in order to perform using the
  language
• Results

gtgtgtgt 4 5 9 gtgtgtgt 4 lt 15 True gtgtgtgt print
me print me gtgtgtgt print print me print me gtgtgt
gt
7
Print Hello World

• Open a terminal window and type python
• If on Windows open a Python IDE such as IDLE
• At the prompt type Hello World !!

gtgtgtgt Hello World !!' Hello World !!'
8
The print Statement

• Elements divided through commas , print with a
  space between them
• The comma at the end from the statement (print
  Welcome,) won't printing the new line character

gtgtgtgt print Welcome Welcome gtgtgtgt print
Welcome, Ram Welcome Ram
9
The Documentation
this symbol is used for starts a comment
gtgtgt gt welcome' welcome' gtgtgt comment' gtgtgt
10
Variables

• Do not need to declare
• Should determine (initialize)
• Using uninitialized variable improves exception
• Certainly not typed
• in case ,friendly greeting Hello World"
• else greeting 122
• print greeting
• Anything is often a variable
• Even characteristics, classes, modules

11
Everything is an object

• Everything means, which includes functions as
  well as classes
• Data type is usually a property of the object
  instead of on the variable

gtgtgtgt x 9 gtgtgt x 9 gtgtgtgt x Welcome gtgtgtgt
x Welcome gtgtgtgt
12
Interactive Shell

• This is good for learning the language
• Good for experimenting for using your library
• Good for testing for using your own modules
• 2 variants IDLE (GUI),python (command line)
• Kind statements or even expressions at prompt

gtgtgtgt print "Hello, World" Hello, World gtgtgtgt x
122 gtgtgtgt x/2 72 gtgtgtgt (this is a comment)
13
Numbers

• The typical suspects
• 13, 3.15, 0xFF, 0377, (-12)3/45, abs(x),
  0ltxlt5
• C-style shifting masking
• 1ltlt17, x0xff, x1, x, xy
• Integer division truncates
• 1/2 -gt 0 1./2. -gt 0.5, float(1)/2 -gt 0.5
• fixed in the future
• Long complicated
• 2L100 -gt 1267650600228229401497607505376L
• Within Python 2.2 as well as past, 2100 will
  the same

14
Strings

• Hello World HelloWorld Concatenation
• Hello2 HelloHello Repetition
• Hello0 h Indexing
• Hello-1 o (From end)
• Hello14 ell Slicing
• len(Hello) 5 Size
• Hellolt jello 1 Comparison
• e in hello 1 Search
• escapes \n etc, \033 etc, \if etc
• 'single quotes' """triple quotes""" r raw
  strings

15
Lists

• Variable arrays, definitely, not Lisp-like linked
  lists
• x 99, on, the, wall
• Exact same providers for strings
• xy, x3, x0, x-1, x1, len(x)
• Item and slice assignment
• x0 98
• -gt 98, on, the, wall
• del x-1 -gt 98

16
Tuples

• Tuples tend to be immutable versions associated
  with lists
• One strange may be the structure to create a
  tuple along with one element
• , is required to differentiate from the
  numerical expression (2)

gtgtgtgt a (1,2,3) gtgtgt gta1 (2, 3) gtgtgtgt b
(2,) gtgtgt gtb (2,) gtgtgt gt
17
Dictionaries

• Some key-value sets
• Dictionaries tend to be mutable

gtgtgt x 1 Welcome', Two' 32, Hi'
4,5,6 gtgtgt x 1 Welcome', Two' 32, Hi'
1, 2, 3 gtgtgt xHi' 4,5,6
18
Standard Library

• Core
• operating system, sys, string, StringIO, struct,
  pickle etc
• Regular expressions
• re module, Perl-5 style patterns as well as
  matching rules
• Web
• socket, rfc822, httplib, htmllib etc
• Miscellaneous
• pdb
• Tkinter, audio etc
