I am trying to setup IDLE to use Python 3 by default in my Fedora 23 computer. Every time I am pulling it up it keeps on using the Python 2 interpreter. Is there a file that I need to configure so that it will utilize the Python 3 interpreter by default?

  • I just did, and it perfectly pulled up IDLE with Python 3 as the interpreter. Nice! Thank you!

python3-tools is a collection of tools included with Python 3 that provides the idle3 program which it installs to /usr/bin/idle3 and it also installs idle3.4 to /usr/bin/idle3.4.

To install python3-tools type:

sudo yum install python3-tools

  • There is also 'python3-tkinter' in the default repos, if you want to save some diskspace.
