How To Get the Python Interpreter on Lubuntu

Ubuntu 1

In this article, we will guide you through the process of getting the Python interpreter on Lubuntu, a lightweight version of Ubuntu. Python is a versatile, high-level programming language that is widely used for web development, data analysis, artificial intelligence, and more. The Python interpreter allows you to execute Python code directly on your Lubuntu system.

Quick Answer

To get the Python interpreter on Lubuntu, simply open the terminal and type python3 to access the interpreter. Lubuntu usually comes with Python pre-installed, so you can check if it’s already installed by using the python3 --version command. If Python is not installed, you can easily install it using the package manager.

Checking for Pre-installed Python

Before we begin, it’s important to note that most Linux distributions, including Lubuntu, come with Python pre-installed. To check if Python is already installed on your system, open the terminal and type the following command:

python3 --version

This command will display the version of Python3 installed on your system. If Python is installed, you will see an output similar to Python 3.x.y.

Accessing the Python Interpreter

To access the Python interpreter, simply type python3 in your terminal and press Enter. This will open the Python interpreter in the terminal, allowing you to write and execute Python code directly.


You will see something like this:

Python 3.x.y
[GCC x.y.z] on linux
Type "help", "copyright", "credits" or "license" for more information.

The >>> is the Python prompt where you can start typing your Python commands.

Creating and Running a Python Script

If you want to write and execute multiple lines of Python code, you can create a Python script file with a .py extension. Here’s how:

  1. Open a text editor from the terminal. For instance, you can use the nano command to open the nano text editor:
  1. In the text editor, write your Python code. For example:
print('Hello, world!')
  1. Save and close the file. In nano, you can do this by pressing Ctrl + X, then Y to confirm saving changes, and finally Enter to confirm the filename.
  2. To execute the code in the file, go back to the terminal and navigate to the directory where the file is located. You can use the cd command to change directories.
  3. Once you are in the correct directory, run the Python script by typing:

This command tells the Python interpreter to execute the code in the file. You should see Hello, world! printed in the terminal.

Locating the Python Interpreter

If you want to find the location of the Python interpreter, you can use the whereis command. This command locates the binary, source, and manual page files for a command.

whereis python3

The output will typically show that the Python3 interpreter is located under /usr/bin/python3.x.


Python is an interpreted language, meaning you don’t need to compile the code before running it. The Python interpreter executes the code directly, making it a convenient tool for writing and testing code. If you’re looking for a more user-friendly interface for writing and executing Python code, consider using an Integrated Development Environment (IDE) like PyCharm or Jupyter Notebook.

How do I install Python on Lubuntu?

Python is usually pre-installed on Lubuntu. You can check if Python is already installed by opening the terminal and typing python3 --version. If Python is not installed, you can install it using the following command: sudo apt-get install python3.

How do I update Python on Lubuntu?

To update Python on Lubuntu, you can use the following command: sudo apt-get install --only-upgrade python3.

Can I use Python 2 on Lubuntu?

Lubuntu primarily supports Python 3. However, you can still install Python 2 alongside Python 3 if needed. To install Python 2, use the following command: sudo apt-get install python2. Keep in mind that Python 2 is no longer actively maintained and Python 3 is recommended for new projects.

How do I install additional Python packages on Lubuntu?

You can use the pip package manager to install additional Python packages on Lubuntu. First, make sure pip is installed by typing pip3 --version in the terminal. If it’s not installed, you can install it using the following command: sudo apt-get install python3-pip. Once pip is installed, you can use it to install packages. For example, to install the numpy package, you can use the command: pip3 install numpy.

How do I uninstall Python from Lubuntu?

It’s generally not recommended to uninstall Python from your system, as it is an essential part of the operating system. Removing Python may cause issues with system functionality. If you need to remove a specific Python version, you can use the apt-get command with the --purge option. For example, to remove Python 3, you can use the command: sudo apt-get --purge remove python3. However, exercise caution when removing Python versions.
