Introduction to Python
def func(): statement 1 statement 2 ………………… ………………… statement N Python is a general-purpose, dynamic, high-level, and interpreted programming language. Python supports multiple programming patterns, including object-oriented, imperative, and functional or procedural programming styles. It was created by Guido van Rossum during 1985- 1990. Python source code is available under the GNU General Public License (GPL). Python has many web-based assets, open-source projects, and a vibrant community. Python is an open-source, cost-free programming language. It is utilized in several sectors and disciplines as a result.
Python Basic Syntax
There is no use of curly braces or semicolon in Python programming language.
In the above example, the statements that are the same level to the right belong to the function. Generally, we can use four whitespaces to define indentation.
Python Features
Readability: Python's syntax emphasizes code readability and uses indentation to define code blocks, making it easy to write and understand code. Versatility: Python can be used for various applications, including web development, data analysis, scientific computing, artificial intelligence, automation, and more. Dynamic Typing: Python uses dynamic typing, allowing variables to change types on the fly, which enhances flexibility and reduces the need for explicit type declarations. Interpreted Nature: Python is an interpreted language, allowing you to execute code directly without needing a compilation step, making development and debugging quicker. Large Standard Library: Python comes with a comprehensive standard library that provides modules and functions for a wide range of tasks, reducing the need to reinvent the wheel. Cross-Platform: Python is cross-platform, meaning code written on one platform can be easily executed on other platforms without significant modifications. Object-Oriented: Python supports object-oriented programming, allowing you to structure code using classes and objects for better organization and reusability. Extensive Third-Party Libraries: Python has a vast ecosystem of third- party libraries and frameworks that simplify complex tasks and accelerate development. Community and Support: Python has a large and active community of developers who contribute to its growth, provide support, and create various resources for learning.
5) Scientific and Numeric
This is the era of Artificial intelligence where the machine can perform the task the same as the human. Python language is the most suitable language for Artificial intelligence or machine learning. It consists of many scientific and mathematical libraries, which makes easy to solve complex calculations.
6) Business Applications
Business Applications differ from standard applications. E-commerce and ERP are an example of a business application. This kind of application requires extensively, scalability and readability, and Python provides all these features.
7) Audio or Video-based Applications
Python is flexible to perform multiple tasks and can be used to create multimedia applications. Some multimedia applications which are made by using Python are TimPlayer, cplay, etc.
8) 3D CAD Applications
The CAD (Computer-aided design) is used to design engineering related architecture. It is used to develop the 3D representation of a part of a system. Python can create a 3D CAD application by using the following functionalities.
9) Enterprise Applications
Python can be used to create applications that can be used within an Enterprise or an Organization. Some real-time applications are OpenERP, Tryton, Picalo, etc.
Python code for "Hello World"
nothing else to type...see how simple is the syntax.
print("Topper World") Topper World
10) Image Processing Application
Python contains many libraries that are used to work with the image. The image can be manipulated according to our requirements.
First Python Program
So before moving on further.. let’s do the most popular ‘HelloWorld’ tradition. Output:
