In this article, we will explain the methods by which you can install IDLE on your Linux system using the command line.

We used the Debian 10 OS to run the commands and procedures mentioned in this article.

Install IDLE

By default, Python is installed in recent releases of Debian and typically comes with an IDLE application. However, if you have a minimal installation without an IDLE application, you can use the following method to install it:

Open a command prompt, Terminal application on your Debian OS. To do this, go to the “Actions” tab, located in the upper left corner of the desktop. Then, in the search menu that appears, find the “Terminal” application and launch it.

Now, first we need to update the package repository. To do this, execute the following command in the terminal:

$ sudo apt-get update

Then, to install IDLE3 on your system, run the following command as sudo in Terminal:

$ sudo apt-get install idle3

Install IDLE 3 IDE

The system will prompt you to continue the installation by providing you with the Y / n option. Press y and installation starts on your system.


Launch IDLE

After installation is complete, you can run IDLE either through the terminal or through the application menu.

To start IDLE through the terminal, enter the following command in the terminal:

$ idle

To start through the application menu, press the super-key on the keyboard and in the search bar that appears, find IDLE using the keyword as follows:

Idle icon

Click on the IDLE icon shown in the results to launch it.

When you run IDLE, the following shell window appears. This allows you to run Python commands and see the results immediately, without having to create a program. The three “more” or “>” characters indicate that your code will begin at this point.

Python shell

For example, let’s try typing something. Place the cursor after the characters “>>>”, then enter the next line and press Enter.

Print (“Hello World!”)

You will get the output as follows:

Python hello World script example

To save this file, select “Save / Save As” in the “File” menu.

In this article, we learned how to install the IDLE Python IDE on a Debian 10 computer. Now you can integrate this Python IDE into your Debian system and take advantage of its easy-to-use GUI-based feature set.
