Introduction to Python

                            


PYTHON(Programing Language)

Python is an interpreted, object oriented, high level programming language. It was developed by Guido Van Rossum in 1985-1990. It is a multi- paradigm programming language. Fortunately an experienced programmer can pick up Python very quickly as it is easy language.

Why python is must?

Fig 1.1

Python is a high-level, interpreted, interactive and object oriented language. Python is degined to highly readable. In python there is less use of English keywords as comparison to other language .

Python is  must for students and working professional to become a great a great software engineer specially when it work in IT sector.

●       Python is interpreted- Python is processed at runtime by the interpreter. You don’t need to compile your program before executing it. It is similar to PHP,PERL.

●       Python is Interactive- you can directly interact with interpreter to write your programs.

●       Python is beginner’s language-  Python is great language for beginners and supports the wide range of applications.

Characteristics Of PYTHON

There are following characteristics of python programming:-

⮚       Its supports functional and structured programming methods as well as OOP.

⮚       It can be integrated by C,C++,JAVA,CORBA.

⮚       It support garbage collection.

Application of Python.

❖    Easy to learn- Python has easy syntax, few keywords, simple structure. Students easily learn this language.

❖    Easy to read- It has well defined Python code.

❖    Database- Python provide interface to commercial database.

❖    GUI Programming- it support GUI application that can be created and ported to many systems.

 History

·         Python was developed in the late 1980 by Guido van Rossum at Centrum Wiskunde & Infomatica (CWI) in the Netherland as a successor to ABC programming language, which was inspired by SETL, capable of exception handling and interfacing with the Amoeba operating system. Its implementation began in December 1989. 

·         Python 2.0 was developed on 16 October 2000,with many new features.

·         Python 3.0 was developed on 3 December 2008.

·         Python 2.7’s end of life date was initially set at 2015 then postponed to 2020 out of concern that a large body of existing code could not easily be forward ported to Python3.

·         Python 3.9.2 and 3.8.8 were expedited as all version of python had security issues, leading to possible remote code execution .

 Why Python is better than other languages

✔       Presence of Third party Modules.

✔       Extensive support Libraries.

✔       Open source and community Development

✔       Learning Ease and support available.

✔       User friendly data structures

✔       Productivity and speed

KEYS IN RDBMS (Data Constraints) Many keys are available in the RDBMS, They allow finding the relation between columns and table that help identify a tuple (row) in a table. They help find a unique record from the table or database.      Keys are seven types in RDBMS Primary key Super key Alternate key Foreign key Candidate key Unique key Composite key                                                                     Fig 1.2 KEYS 1.       PRIMARY KEY A primary key is an attribute (columns) of a table or group of columns that uniquely identify each record in a table.

Hackers are the computer expert who by their computer skills find a loop hole to achieve a goal or target within a computerized system in a illegal manner. Today computer is mandatory part to do a professional work or to handle a successful business. We can have private system for using purpose because we need networks to interact and fetch data so computers are connected in networks which make them prone for hacking and cyber crime. Which cause them a lot of loss of information and money. Types Of Hacking Hacking can be broadly classified in two parts :- 1.     Ethical Hacking –Ethical Hacking is a hacking which is contracted with the government, private organization or ...
