Python-Can I get some help with this ModuleError

[buran]

You must learn to describe clearly a problem you have.

The program works fine if I run it on Pycham but if I try to run it on IDLE 3.9 it displays an error.

Your description in the first post does not reconcile with your later explanation about that import line. There is no way it worked fine in PyCharm, given there is no module k.

Unless there was a k.py file somewhere in pycharm's search path. That is more in line with pycharm offering ro add an import line. When running with IDLE are you using the same code in the same folders?

That was my initial guess, based on the first OP post

Is k a module (py file) located next to your script in PyCharm project folder?

And they didn't respond affirmative

And from same CWD
