ModuleNotFoundError: No module named 'com'

Thank you.
Actually, I'm Java developer. So, as usual, I have created the class in a certain package

package com.my.pack1
class MyClass {
}

Now I'm trying to utilize the same approach in Python.
So I've created the package 'com.my.pack1' and class 'MyClass' there.
I've created the test and trying to launch it. The structure of the project

Maybe some additional settings should be made?
