What is Python? #
Python is an interpreted, object-oriented, and high-level language with dynamic semantics. It is free and open source. And thanks to its built-in data structures and dynamic prowess, Python is perfect for Rapid Application Development and scripting . It's your go-to for creating web apps, orchestrating workflows, and connecting to databases. Need to crunch big data or tackle complex math? Python's got your back. It is used for crafting rock-solid, production-ready software, too. Other applications of Python include the following:
Artificial intelligence
Natural language processing tasks
Development in the information security industry
Game Development
GUI-based desktop applications
Google, YouTube, Dropbox, Microsoft, Cisco, and Spotify are just some of the organizations that use Python. Some powerful features of Python include its sizable standard library, dynamic memory allocation, multiple library options, and ease of debugging. So, whether coding for fun or for a work project, you can trust Python. Now that you know what Python is used for, let's see how you should start learning.
Beginning Python #
Start by taking a look at some simple code samples. It'll benefit you if you do this before starting any tutorial. You must be familiar with the command line or terminal, IDEs (integrated development environments), and text editors to simplify Python editing.
Python Installation#
For an optimal user experience, check if your system fulfills the following hardware and software requirements:
Memory: A minimum of 4 GB of RAM is advisable, but having more is advantageous, especially when dealing with extensive datasets or resource-demanding applications.
Storage: Ensure you have at least 5 GB of disk space for the Python installation. Allocate additional space for the libraries, packages, and project files you intend to employ.
Any of the following operating systems:
Windows (Windows 7 and later)
MacOS (macOS 10.9 and later)
Linux (any of the distributions, such as Ubuntu, Fedora, and CentOS)
Here's a generalized installation guide for Python on different operating systems:
Windows:
Download the Python installer.
Run the installer.
Customize the installation (optional).
Proceed with the installation.
Verify the installation.
Or, consider using the Microsoft Store for installation.
MacOS:
Check your current Python version.
Visit the Python website.
Download the macOS installer.
Run the installer and follow the instructions.
Verify Python and IDLE installations.
Confirm installation via Terminal.
Linux:
Check for pre-installed Python.
Use the Package Manager to install or update Python.
If needed, download the latest Python version.
Compile from source (optional).
Configure the script and complete the build process.
Verify the installation.
OR just skip the installation and start practicing now. Our courses offer an in-browser coding environment for a hassle-free, hands-on experience. If you need a primer to start your Python coding journey, Programming in Python is an excellent beginner course.
Python Sample Code #
Let's look at a sample of Python code to better understand Python syntax. Python coding differs from many programming languages because it uses new lines to conclude commands instead of semicolons or parentheses. It also defines the scope—including loops, functions, and classes—through indentation rather than using curly brackets.
