IDLE shares its import mechanism with every other Python script. 

This results in the nasty quirk that if you have other .py files in the same 
directory as mypythoncodes.py, and one of these files has the same name as 
one of the modules in Python's standard library IDLE will try to run with 
your module rather than the one it actually needs. Common candidates are 
code.py or string.py, but there are many more. 

Once you rename or delete those files IDLE should start working again.

PS: Judging from the traceback in your answer to eryk sun in your case the 
offending module may be called tkinter.py
