Certainly! Running Python in the terminal on Linux is a fundamental skill for any Python developer. In this tutorial, I'll guide you through the process of running Python scripts, using the interactive Python shell, and installing Python packages using the terminal.
Before you can run Python in the terminal, you need to ensure that Python is installed on your Linux system. Most Linux distributions come with Python pre-installed. To check your Python version or install it, open the terminal and type:
If Python is not installed, you can install it using your package manager. For example, on Ubuntu or Debian-based systems, you can use:
Replace apt-get with your distribution's package manager if you're not using a Debian-based system.
Open the terminal on your Linux system. You can usually find it in your applications menu or use the keyboard shortcut Ctrl + Alt + T.
Create a new Python script using your preferred text editor. Let's say we create a simple script called hello.py:
Save the file and navigate to its directory in the terminal using the cd command:
Now, run the Python script:
This should output:
You can also run Python interactively in the terminal. Type python3 to start the Python interactive shell:
This opens the Python REPL (Read-Eval-Print Loop). You can enter Python code directly:
Exit the interactive shell by typing exit() or pressing Ctrl + D.
To install Python packages, you can use the package manager pip. For example, to install the requests library, type:
Replace requests with the name of any Python package you want to install.
That's it! You've learned how to run Python in the terminal on Linux, execute scripts, use the interactive shell, and install Python packages. These skills are essential for any Python developer working on a Linux system.
