title: getting started with python 3 on linux: a comprehensive tutorial
introduction:
python is a versatile and powerful programming language that is widely used for various applications, ranging from web development to scientific computing. in this tutorial, we will guide you through the process of getting started with python 3 on a linux system. we’ll cover installation, basic usage, and provide code examples to help you build a solid foundation.
before proceeding, check if python 3 is already installed on your linux system. open a terminal and run the following command:
if python 3 is not installed, you can install it using the package manager specific to your linux distribution.
using virtual environments helps isolate your python projects and dependencies. it’s a good practice to create one for each project. to create a virtual environment, run the following commands:
create a simple “hello world” python script. open your favorite text editor and create a file named hello.py:
save the file and run it from the terminal:
you should see the output:
pip is the package installer for python. to install a package, use the following syntax:
for example, to install the popular requests library:
python comes with an interactive shell, commonly known as the repl (read-eval-print loop). open the python shell by running:
you can then enter python code directly in the shell and see the results immediately.
congratulations! you’ve successfully set up python 3 on your linux system and created a simple python script. this tutorial provides a solid foundation for further exploration and development with python on linux. feel free to explore more advanced topics like web development, data science, or automation using python. happy coding!
