Python 3.5.1 is installed on Ubuntu 16.04 by default. You can verify that by running the command python3 --version
in a terminal.
Now, IDLE for Python 3 is in the package idle3
and part of the default Python distribution but it's not installed on Ubuntu by default. You can do so with Software Center or your favourite package manager. On the command-line you can run:
sudo apt-get install idle3
If that gives you an error as you say in the comments, please edit your question with the "edit" link below it to include the error messages verbatim (and send me a message in the comments to notify me of the change), or ask a new question with the same information.
which python3
andpython3 --version
and give us the outputs? – edwinksl Jun 20 '16 at 17:18which python3
say? I want to make sure Python 3 is already on your system. As for your question regarding IDLE, IDLE is not installed by default. There is no reason why Python 3 must come together with IDLE. If you want it, dosudo apt install idle3
