In Python 2.5.4's config-main.cfg file, if [EditorWindow]'s width and height are left blank or set to zero, then IDLE window won't show. Uninstalling and re-installing Python didn't help. Problem solved only when the config-main.cfg file was manually edited to give non-zero values.
mdickinson commentedon Nov 20, 2012
Thanks for the bug report. Are you in a position to test whether this is still an issue for Python 2.7? (Python 2.5 is no longer maintained.)
serwy commentedon Nov 20, 2012
This is still a bug with 2.7 and 3.4. I just tried leaving the width and height fields in config-main.cfg and IDLE had raised the error:
The width and height keys in the text_options dictionary in EditorWindow.py are set to blank strings instead of a number of a number as a string.
IDLE not showing up is a symptom of bpo-13582.
serhiy-storchaka commentedon Nov 20, 2012
When width or height are 0, IDLE starts and show window with some minimal width or height. When width or height are empty or invalid IDLE can't start.
The proposed patch makes IDLE more resistant against such broken configs.
serwy commentedon Nov 20, 2012
Serhiy, I applied your patch and it works. However, the initial window size in IDLE Preferences->General are listed as "None" instead of a number.
Perhaps if the userCfg has an invalid value then the defaultCfg should be returned?
serwy commentedon Nov 20, 2012
Changed from Crash to Behavior, as the interpreter is not crashing. Also undid my mistake of re-adding 2.6 and 3.1.
serhiy-storchaka commentedon Nov 20, 2012
Yes, you are right. Thanks for suggestion.
serhiy-storchaka commentedon Nov 20, 2012
Patch updated. Added warning for case when user config broken. Thanks Roger for suggestion.
doanviettrung commentedon Nov 21, 2012
Suggestion: When Python is installed, it starts its configurations files
afresh.

Fixed.
Trung, I think installation procedure is not subject of this issue.
If needed please create new one.
doanviettrung commentedon Dec 24, 2012
I think I will leave it at that, because in the general case probably some
things should be re-initialised during a new/re-install while others should
be left as is, but as a beginner I am far from knowing which ones are which.
