Hi MrE.Merry,


There may be a file clashing with the normal python files. 

I guess, you could take a look into your Python directory, and see if you have .py file which has a name of another python module/keyword, causing it to conflict with the normal module in python. Remove that/those files, or move that/those files to some other directory, and see if IDLE starts working for you again. I would suggest you look in your main python directory and see if there are any .py files that you could move to different places.

Or, simply, you can cut all files with .py extension, paste them in a place different from the os path. Run the IDLE again.
