Question

How do I make Python 2.7 the default in Idle instead of it launching 3?

Answer 1

I think you can do it simply by reinstalling 2.7 (the last install becomes default).

Is this Windows? When you say it launches 3, in what sense? When you click a .py file?

Answer 2

What is the difference, anyway? I don't even know WHAT I'm running...

Answer 3

For the duration of the course, you might want to consider just uninstalling 3 if you have no use for it at the moment.

It will cause problems with the coursework.

Answer 4

Thanks!

Answer 5

python 2.7 has a much messier object-oriented programming style but python three has those brackets after the print function, apart from removing class initiation in classes.

Answer 6

It depends on the disto.

e.g. in Gentoo you’d solve this with `eselect python set python2.7` (which happens to be the default)
