I am an slightly more than a beginner.
I have not met this advice from Steven D'Aprano before, so I have some
questions.
I have constructed a program which has a parent class and a child class
and I have them in two different files. I import the parent class into
the child class and create instances with the child class. This works fine.
But, would it be better to have both classes in one file? Would then the
child class 'know' that the parent class is in the file?
And further. I have a function which sets up all the suitable data
structures into which this function will put the information supplied by
the user. I import this file too into both the parent and the child class.
Would the instances with which I actually work, 'know' that this
function is there if it is simply present in the same file?
