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

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.

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:

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