As You can see, i can't assign the new value "os.path.join(root, f)" to
the 'self._this_module variable'.
In the __init__ method, you successfully set the `_this_module` attribute:
self._this_module = ''
That works, so it proves that you *can* set a private attribute.
Later on, you call the `_SetVar` method, which does this:
def _SetVar(self, attr, val):
self.attr = val
In English, this method does this:
(1) Take two arguments, and store them in variables called "attr" and
"val".
(2) Assign the value stored in "val" to an attribute named exactly "attr".
What you actually want is:
(1) Take two arguments, and store them in variables called "attr" and
"val".
(2) Assign the value stored in "val" to an attribute with the name stored
in the variable "attr".
Can you see the difference?
What you actually want is:
def _SetVar(self, attr, val):
setattr(self, attr, val)
Your code is terribly complicated. This will probably do what you want.

I changed the name of print_module_text because it doesn't actually print
anything.
