Please I installed Idle3. But when I launched it by typing Idle from the terminal, it loaded python3.6.6 by default. If I search Idle under applications There are three options:

  1. Idle
  2. Idle using python 3.6.6
  3. Idle using python 3.7.0

My question is: Is it possible to change the default idle that opens when I type Idle from terminal?

Thank you

This question is a possible duplicate of Python IDLE:Change Python Version`

But in any case. Here's what you can do: In your terminal type

sudo nano /usr/bin/idle-python3.6.6

The first line should look something like this

/usr/bin/python3.6.6

Change the end of the line to the version you are looking for idle to open by defauly (3.7.0 in your case).

Hope that helps:) oh and welcome to stackoverflow

If you do:

which idle

You get the path which is used for running idle, e.g. /usr/bin/idle

I'm guessing a bit but I think that it might be a soft link that points to the 3.6.6 version of idle. If so, you can see where the soft link points by doing 

ls -l /usr/bin/idle

That would return something like "/usr/bin/idle -> /usr/bin/idle3.6.6" To update the soft link, use ln with -f:

ln -s -f /usr/bin/idle3.7.0 /usr/bin/idle

And that should hopefully update the link to use the later version. Do note that I have assumed the /usr/bin path for the executables, it might be different in your case.
