Introduction to Python
Python is a high-level, interpreted programming language created by Guido van Rossum in the late 1980s. It was designed with simplicity and readability in mind, making it an excellent choice for both beginners and professionals. Python’s unique syntax emphasizes code readability, allowing developers to express concepts in fewer lines of code than other languages.Python has gained immense popularity and has become one of the most widely used programming languages in the world.
In the below PDF we discuss about Introduction To Python in detail in simple language, Hope this will help in better understanding.
Characteristics and features of Python:
- High-Level Language: Python is a high-level programming language, which means it abstracts many low-level details like memory management and hardware interactions. This makes it easier to write and read Python code compared to lower-level languages like C or assembly.
- Interpreted Language: Python is an interpreted language, which means that you don’t need to compile your code before running it. Instead, an interpreter reads and executes the code line by line, making development and debugging faster.
- Readable and Clean Syntax: Python is famous for its clean and readable syntax. It uses indentation (whitespace) to define code blocks, which enforces good coding practices and makes the code easy to understand. This readability is often referred to as the “Pythonic” way of writing code.
- Versatility: Python is a multipurpose language. It can be used for a wide range of applications, including web development, data analysis, scientific computing, artificial intelligence, machine learning, automation, and more. There are libraries and frameworks available for almost every domain, making Python a versatile choice.
- Large Standard Library: Python comes with a vast standard library that contains modules and packages for various tasks. This library provides a wide range of pre-written code that simplifies common programming tasks, reducing the need to write code from scratch.
- Cross-Platform Compatibility: Python is cross-platform, meaning you can write code on one operating system (such as Windows, macOS, or Linux) and run it on another without modification. This portability is a significant advantage when developing software for different platforms.
- Dynamic Typing: Python uses dynamic typing, which means you don’t need to declare variable types explicitly. The interpreter determines the data type at runtime, making Python code concise and flexible.
- Strong Community: Python has a large and active community of developers. This community contributes to the language’s growth by creating libraries, frameworks, and tools, and providing support through forums, mailing lists, and conferences.
- Open Source: Python is an open-source language, which means its source code is freely available and can be modified and distributed by anyone. This open nature has contributed to its widespread adoption.
- Extensibility: Python can be easily extended by integrating with code written in other languages, such as C and C++. This allows developers to leverage existing codebases and libraries when needed.
Python is a high-level, interpreted programming language known for its simplicity and readability. It was created by Guido van Rossum and first released in 1991.
Python is popular because it’s easy to learn, has a clean and concise syntax, and a vast standard library. It’s versatile and can be used for web development, data analysis, artificial intelligence, and more.
Comments in Python start with the # character. Anything after # on a line is treated as a comment and is not executed by the Python interpreter.
Indentation in Python is used to define blocks of code. It is essential for structuring the code and determining the scope of functions, loops, and conditionals.
Python can be used for web development using frameworks like Django and Flask. These frameworks simplify web application development by providing tools and libraries for handling web-related tasks.
