ModuleNotFoundError: No module named 'xxx' and NameError: name 'xxx' is not defined

[y1y2]

I called python in kotlin and started reporting ModuleNotFoundError: No module named 'xxx'.
I added

import sys to the corresponding py file
import os
current_dir = os.path.dirname(os.path.abspath(file))
sys.path.append(current_dir)

Solution: NameError: name 'xxx' is not defined after recompilation
The suspect is from xxx import *, which is caused by mutual import, as shown in the figure, all.py files are custom.

I don't understand your file layout, what is xxx? Where is it imported?
Does your python code work under CPython?

There is already a module named java in the standard library, it could be causing problems. Please rename the module or put all your modules into a package to namespace it.

I tried to modify the file name of java.py for java execution
”context.eval(source)“
No problem, but I use
“ctx.getBindings(mainScriptType).getMember("a").execute()”
Call a function a() in a.py, which calls the b() method in another b.py file with a
“NameError: name 'xxx' is not defined”,
xxx is a reference to a function under b(),
if I move b() to the a.y file, there is no problem, this has been troubling for a long time.
