Programming Language Tutorial And All Important Things

Introduction :-

Python is a programming language.
Python can be used on a server to create internet applications.

What is Python?

Python is a famous programming language. It was once created via Guido van Rossum, and launched in 1991.
It is used for:
web improvement (server-side),
software development,
mathematics,
system scripting.

What can Python do?

Python can be used on a server to create net applications.
Python can be used alongside software program to create workflows.
Python can join to database systems. It can additionally study and alter files.
Python can be used to cope with huge facts and operate complicated mathematics.
Python can be used for speedy prototyping, or for production-ready software program development.

Why Python?

Python works on specific structures (Windows, Mac, Linux, Raspberry Pi, etc).
Python has a easy syntax comparable to the English language.
Python has syntax that permits builders to write applications with fewer strains than some different programming languages.
Python runs on an interpreter system, which means that code can be done as quickly as it is written. This skill that prototyping can be very quick.
Python can be dealt with in a procedural way, an object-orientated way or a practical way.
Good to know
The most latest predominant model of Python is Python 3, which we shall be the usage of in this tutorial. However, Python 2, even though now not being up to date with something different than protection updates, is nevertheless pretty popular.
In this tutorial Python will be written in a textual content editor. It is viable to write Python in an Integrated Development Environment, such as Thonny, Pycharm, Netbeans or Eclipse which are specially beneficial when managing large collections of Python files.
Python Syntax in contrast to different programming languages
Python was once designed for readability, and has some similarities to the English language with affect from mathematics.
Python makes use of new traces to entire a command, as adverse to different programming languages which regularly use semicolons or parentheses.
Python depends on indentation, the usage of whitespace, to outline scope; such as the scope of loops, features and classes. Other programming languages regularly use curly-brackets for this purpose.

Python Install

Many PC,Laptop Will Already Have Python Installed.
For Check Just Open Command Prompt And Write python --version And Enter.
if You Not Installed Then Visit https://www.python.org/ And Install Python.

Python Hello World Program

Create a New File In Any editor like notepad++, sublime text editor.
And Write print("Hello World!!") And Save That File With filename.py extension use .py After Your Filename, This .py Extension Is Indicate Python.
Now Run This File In Command Prompt C:\Path Of Your File\python filename.py Then Enter.
Outpur is :- Hello World!!

Applications of Python

As referred to before, Python is one of the most extensively used language over the web. I'm going to listing few of them here:

Easy-to-learn − Python has few keywords, easy structure, and a truly described syntax. This approves the scholar to pick out up the language quickly.
Easy-to-read − Python code is extra without a doubt described and seen to the eyes.
Easy-to-maintain − Python's supply code is pretty easy-to-maintain.
A extensive popular library − Python's bulk of the library is very transportable and cross-platform well suited on UNIX, Windows, and Macintosh.
Interactive Mode − Python has aid for an interactive mode which lets in interactive trying out and debugging of snippets of code.
Portable − Python can run on a extensive range of hardware systems and has the identical interface on all platforms.
Extendable − You can add low-level modules to the Python interpreter. These modules allow programmers to add to or customise their equipment to be greater efficient.
Databases − Python presents interfaces to all important industrial databases.
GUI Programming − Python helps GUI purposes that can be created and ported to many machine calls, libraries and home windows systems, such as Windows MFC, Macintosh, and the X Window machine of Unix.
Scalable − Python offers a higher shape and help for giant packages than shell scripting.

Prerequisites

You need to have a primary appreciation of Computer Programming terminologies. A primary perception of any of the programming languages is a plus.

Python is Interpreted − Python is processed at runtime by way of the interpreter. You do no longer want to collect your software earlier than executing it. This is comparable to PERL and PHP.

Python is Interactive − You can truely sit down at a Python immediate and have interaction with the interpreter at once to write your programs.

Python is Object-Oriented − Python helps Object-Oriented fashion or method of programming that encapsulates code inside objects.

Python is a Beginner's Language − Python is a awesome language for the beginner-level programmers and helps the improvement of a vast vary of purposes from easy textual content processing to WWW browsers to games.

History of Python

Python used to be developed by way of Guido van Rossum in the late eighties and early nineties at the National Research Institute for Mathematics and Computer Science in the Netherlands.
Python is derived from many different languages, together with ABC, Modula-3, C, C++, Algol-68, SmallTalk, and Unix shell and different scripting languages.
Python is copyrighted. Like Perl, Python supply code is now reachable underneath the GNU General Public License (GPL).
Python is now maintained by using a core improvement group at the institute, though Guido van Rossum nevertheless holds a necessary function in directing its progress.

Python Features

Python's aspects encompass −

Easy-to-learn − Python has few keywords, easy structure, and a genuinely described syntax. This lets in the scholar to choose up the language quickly.
Easy-to-read − Python code is greater really described and seen to the eyes.
Easy-to-maintain − Python's supply code is pretty easy-to-maintain.
A huge wellknown library − Python's bulk of the library is very transportable and cross-platform well matched on UNIX, Windows, and Macintosh.
Interactive Mode − Python has help for an interactive mode which permits interactive trying out and debugging of snippets of code.
Portable − Python can run on a large range of hardware structures and has the identical interface on all platforms.
Extendable − You can add low-level modules to the Python interpreter. These modules allow programmers to add to or customise their equipment to be extra efficient.
Databases − Python affords interfaces to all fundamental industrial databases.
GUI Programming − Python helps GUI functions that can be created and ported to many gadget calls, libraries and home windows systems, such as Windows MFC, Macintosh, and the X Window machine of Unix.
Scalable − Python offers a higher shape and guide for massive applications than shell scripting.

Apart from the above-mentioned features, Python has a large listing of suitable features, few are listed under −

It helps purposeful and structured programming techniques as nicely as OOP.
It can be used as a scripting language or can be compiled to byte-code for constructing massive applications.
It presents very high-level dynamic information sorts and helps dynamic kind checking.
It helps automated rubbish collection.
It can be effortlessly built-in with C, C++, COM, ActiveX, CORBA, and Java.

What Are Frameworks In Python?

A framework is a series of modules or applications which helps in writing net applications. While working on frameworks in python we don’t have to fear about the low stage small print such as protocols, sockets or thread management.
Frameworks automate the frequent implementation of frequent options which offers the flexibility to the customers to center of attention on the software common sense as a substitute of the primary hobbies processes.
Frameworks make the existence of net builders simpler with the aid of giving them a shape for app development. They furnish frequent patterns in a net utility that are fast, dependable and effortlessly maintainable.

The use of a net framework:

Url Routing – Routing is the mechanism of mapping the URL immediately to the code that creates the internet page.
Input structure coping with and validation – Suppose you have a structure which takes some input, the concept is to validate the statistics and then keep it.
Output codecs with template engine – A template engine permits the builders to generate favored content material kinds like HTML, XML, JSON.
Database connection – Database connection configuration and chronic facts manipulation via an ORM.
Web protection – Frameworks provide net protection in opposition to cross-site request forgery aka CSRF, sql injection, cross-site scripting and different frequent malicious attacks.
Session storage and retrieval – Data saved in the session storage receives cleared when the web page session ends.

Advantages Of Frameworks

Open-source
Good documentation
Efficient
Secure
Integration
