If a file named "tkinter.py" is created and tkinter is imported and used within
the file, the following exception is raised:
"AttributeError: partially initialized module 'tkinter' has no attribute 'Tk'
(most likely due to a circular import)"

Great that you point that out. I have thought of are two possible solutions to
this:
1. Make the current error message clearer, but make sure that it's correct for
both cases
2. Create a special case for trying to import itself.
I personally think the second option would be superior. If necessar

It would have non-zero cost. There is a common idiom:
try:
from foo import bar
except ImportError:
def bar
I actually didn't know that there were use cases for importing itself — thanks
for letting me know.
The best way of implementing a better error message would probably be to change
the message for when the user import itself, while it's still partially
initialized.
