In most of today’s modern Linux distributions, Python is installed by default and it comes with the IDLE application. However, If isn’t installed, you can install it using your default package manager as shown
sudo apt install idle [On Debian/Ubuntu for Python2]
$ sudo apt-get install idle3 [On Debian/Ubuntu for Python3]
$ sudo yum install python3-tools [On CentOS/RHEL and Fedora]
