Python Programming Language

Python is a high-level, general-purpose and a very popular programming language. Python programming language (latest Python 3) is being used in web development, Machine Learning applications, along with all cutting edge technology in Software Industry. Python Programming Language is very well suited for Beginners, also for experienced programmers with other programming languages like C++ and Java.

This specially designed Python tutorial will help you learn Python Programming Language in most efficient way, with the topics from basics to advanced (like Web-scraping, Django, Deep-Learning, etc.) with examples.

Below are some facts about Python Programming Language:

1. Python is currently the most widely used multi-purpose, high-level programming language.
2. Python allows programming in Object-Oriented and Procedural paradigms.
3. Python programs generally are smaller than other programming languages like Java. Programmers have to type relatively less and indentation requirement of the language, makes them readable all the time.
4. Python language is being used by almost all tech-giant companies like – Google, Amazon, Facebook, Instagram, Dropbox, Uber… etc.
5. The biggest strength of Python is huge collection of standard library which can be used for the following:
   • Machine Learning
   • GUI Applications (like Kivy, Tkinter, PyQt etc. )
   • Web frameworks like Django (used by YouTube, Instagram, Dropbox)
   • Image processing (like OpenCV, Pillow)
   • Web scraping (like Scrapy, BeautifulSoup, Selenium)
   • Test frameworks
   • Multimedia
   • Scientific computing
   • Text processing and many more..

JAVA

Java is one of the most popular and widely used programming languages.

• Java has been one of the most popular programming languages for many years.
• Java is Object Oriented. However, it is not considered as pure object-oriented as it provides support for primitive data types (like int, char, etc)
• The Java codes are first compiled into byte code (machine-independent code). Then the byte code runs on Java Virtual Machine (JVM) regardless of the underlying architecture.
• Java syntax is similar to C/C++. But Java does not provide low-level programming functionalities like pointers. Also, Java codes are always written in the form of classes and objects.
• Java is used in all kinds of applications like Mobile Applications (Android is Java-based), desktop applications, web applications, client-server applications, enterprise applications, and many more.
• When compared with C++, Java codes are generally more maintainable because Java does not allow many things which may lead to bad/inefficient programming if used incorrectly. For example, non-primitives are always references in Java. So we cannot pass large objects (like we can do in C++) to functions, we always pass references in Java. One more example, since there are no pointers, bad memory access is also not possible.
• When compared with Python, Java kind of fits between C++ and Python. The programs are written in Java typically run faster than corresponding Python programs and slower than C++. Like C++, Java does static type checking, but Python does not.

C++

C++ is a general-purpose programming language and is widely used nowadays for competitive programming. It has imperative, object-oriented and generic programming features. C++ runs on lots of platforms like Windows, Linux, Unix, Mac etc.

Perl

Perl is a general purpose, high level interpreted and dynamic programming language. Perl supports both the procedural and Object-Oriented programming. Perl is a lot similar to C syntactically and is easy for the users who have knowledge of C, C++. Since Perl is a lot similar to other widely used languages syntactically, it is easier to code and learn in Perl. Programs can be written in Perl in any of the widely used text editors like Notepad++, gedit, etc.

Golang

Golang is a procedural and statically typed programming language having the syntax similar to C programming language. Sometimes it is termed as Go Programming Language. It provides a rich standard library, garbage collection, and dynamic-typing capability. It was developed in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson at Google but launched in 2009 as an open-source programming language and mainly used in Google’s production systems. Golang is one of the most trending programming languages among developers.

SQL

Structured Query Language or SQL is a standard Database language which is used to create, maintain and retrieve the data from relational databases like MySQL, Oracle, SQL Server, PostGre, etc. The recent ISO standard version of SQL is SQL:2019.

C#

C# is a general-purpose, modern and object-oriented programming language pronounced as “C Sharp”. It was developed by Microsoft led by Anders Hejlsberg and his team within the .NET initiative and was approved by the European Computer Manufacturers Association (ECMA) and International Standards Organization (ISO). C# is among the languages for Common Language Infrastructure. C# is a lot similar to Java syntactically and is easy for users who have knowledge of C, C++ or Java.

PHP

The term PHP is an acronym for Hypertext Preprocessor. It is a server-side scripting language that is used for web development. It can be easily embedded with HTML files. HTML codes can also be written in a PHP file. The PHP codes are executed on the server-side whereas HTML codes are directly executed on the browser.

Why we learn PHP ?

It is one of the widely used open-source general-purpose scripting language that is used for backend Development. Apart from this, let’s see why we should learn it.

• Easy to Learn: It is easier to learn for anyone who has come across to any programming language for the first time.
• Free of Cost: Since it is an open-source language, therefore developers are allowed to use its components and all methods for free.
• Flexible: Since It is a dynamically typed language, therefore there are no hard rules on how to build features using it.
• Supports nearly all databases: It supports all the widely used databases, including MySQL, ODBC, SQLite etc.
• Secured: It has multiple security levels provides us a secure platform for developing websites as it has multiple security levels.
• Huge Community Support: It is loved and used by a huge number of developers. The developers share their knowledge with other people of the community that want to know about it.

Kotlin

Scala is a general-purpose, high-level, multi-paradigm programming language. It is a pure object-oriented programming language which also provides support to the functional programming approach. Scala programs can convert to bytecodes and can run on the JVM (Java Virtual Machine). Scala stands for Scalable language. It also provides Javascript runtimes. Scala is highly influenced by Java and some other programming languages like Lisp, Haskell, Pizza etc.
