"Edit with IDLE" doesn't work any more ?

[Yip, Kin]

Hi Erky and Peter,

Thanks for the explanations.   Next time, I'd try to treat the "traceback" more seriously :-)
I've learnt the difference between python.exe and python.exe   and   to be more carefully with my code names :-(

The traceback tells you what you need to know. See how importing tkinter used your "Python Codes\tkinter.py".

The first part of this problem is that "Edit with IDLE" is executed as `pythonw.exe -m idlelib "%L" %*`. The -m command-line option adds the working directory (not the script directory) to the head of sys.path.
The second part is that Explorer starts the process with the working directory set to the parent directory of the "%L" target file. The 3rd part is that you have a file in that directory named tkinter.py.
Overall this is a bad experience for beginners, and I know Terry Reedy is working to improve this.
