Python Introduction
What is Python?
Python is a widely known programming language that has been around since 1991. It was developed by Guido van Rossum with the intention of creating a language that is easy to read, write, and understand.
Today, Python is commonly used in areas such as:
- Server-side web development
- General software development
- Mathematical and scientific computing
- Automation and system-level scripting
What Can Python Do?
Python is a flexible language that can be applied to many different tasks.
- It can run on servers to build and manage web-based applications.
- It can work together with other software tools to automate workflows and processes.
- It is capable of connecting to databases and can read, update, and manage files.
- It is frequently used for handling large datasets and performing advanced mathematical operations.
- It supports both quick experimentation and full-scale, production-ready software development.
Why Python?
Python is chosen by beginners and experienced developers alike for several strong reasons.
- It runs smoothly on many platforms, including Windows, macOS, Linux, and devices like Raspberry Pi.
- Its syntax is designed to be simple and close to natural English, making it easier to learn.
- Many tasks can be completed with fewer lines of code compared to other programming languages.
- Python uses an interpreter, allowing code to be executed immediately after it is written, which speeds up testing and prototyping.
- It supports multiple programming styles, including procedural, object-oriented, and functional approaches.
Good to Know
- Python 3 is the latest major version and is the version used throughout this tutorial.
- Python programs can be written using a basic text editor, but many developers prefer using Integrated Development Environments (IDEs). Tools such as Thonny, PyCharm, NetBeans, and Eclipse are especially helpful when working with larger Python projects.
Python Syntax Compared to Other Programming Languages
Python was created with readability as a top priority. Its syntax closely resembles plain English and includes concepts inspired by mathematics.
- Python uses new lines to end commands, unlike many languages that rely on semicolons or parentheses.
- Indentation and whitespace are used to define code blocks, such as loops, functions, and classes. In contrast, many other languages use curly braces to define scope.
