Start IDLE with python 3 on Linux (python 2.7 installed alongside)
Solution 1
You'd have to install the appropriate package - Python 2.x and 3.x aren't compatible with each other.
You can find the link here.
Solution 2
Just type sudo apt-get install idle3
in your terminal and idle for your version of Python 3 previously installed will be installed.
Then both are compatible. You run the 2.7 idle from your terminal by just typing idle
. And you run the idle 3 version by just typing idle3
in the terminal. That worked for me.
Solution 3
I had to install python3-tools to get idle3 (using Fedora 18).
Solution 4
I installed idle using the following command:
sudo yum install python-tools.x86_64
And I can run both the command and gives me python2 or 3 shell respectively:
idle
idle3
Solution 5

sudo yum install python3-tools
This also works on Fedora 19.

I initially had python 2.7, which often comes bundled with the OS (currently using Linux Mint 12). I wanted to try python 3, so I installed it alongside python 2. All fine there, I can run both versions in terminal by calling either
python
orpython3
. However, there seems to be no way to start IDLE with python 3. Is there some flag that I can pass to IDLE when I start it so that I can pick which version of python I would like it to run?E.g. (these don't work)
idle3
oridle --shell=python3
or something like that. Hope you get what I mean. I read about pointing to a different executable in this question about IDLE for Python 3 (on Vista). However, I can't seem to do the analogous thing on Linux.
