The Internet enables the selling of goods and services in online mode. In fact, People have started using the word Google as a generic verb synonymous to search. One can search on anything on this site, and the search question can be in any format. Google, Yahoo, and MSN are the renowned search engines in use today. These engines locate the information one seeks, available in whichever server across the globe (world wide web). FTP concept is still in use even today in mobile apps for files downloading. Normally E-mail restricts the size of a file that can be shared, and also, it is not secured to share sensitive and confidential data across public networks. The data exchange may occur between two business entities or customers with business and vice versa. FTP is the file transfer protocol that enables data exchange between two stakeholders over internet media in a secure way. This is the second major use case for the internet in the early days. Email concepts paved the way for developing many innovative tools for improved collaboration.

Compound Statements and Indentation: Python uses indentation to indicate body-block.(C/C++/C#/Java's statement ends with a semi-colon ( )) Statements: Python's statement ends with a newline.Data Types: Python support these data types: int (integers), float (floating-point numbers), str (String), bool (boolean of True or False), and more.(In C/C++/C#/Java, you need to declare the name and type of a variable before using it.) Python associates types with the objects, not the variables, i.e., a variable can hold object of any types. A variables is created via the initial assignment. You do NOT need to declare variables (name and type) before using them. Variable Type Declaration: Like most of the scripting interpreted languages (such as JavaScript/Perl), Python is dynamically typed.(C/C++/C#/Java use double quotes for string and single quotes for character. Python also supports multi-line string, delimited by either triple-single ( '''.''') or triple-double quotes ( """."""). String: Python's string can be delimited by either single quotes ( '.') or double quotes ( ".").(C/C++/C#/Java end-of-line comment begins with '\\'. Python does not support multi-line comments. Comment: Python's comment begins with a '#' and lasts until the end-of-line.This section is for experienced programmers to look at Python's syntaxes and those who need to refresh their memory. I personally recommend that you learn a traditional general-purpose programming language (such as C/C++/Java) before learning scripting language like Python/JavaScript/Perl/PHP because they are less structure than the traditional languages with many fancy features. This article is NOT meant to be an introduction to programming. I shall assume that you are familiar with some programming languages such as C/C++/Java.
