UML component diagram for Python code: How to illustrate difference between classes and modules?

Question

I need to draw an UML component diagram for my code / a scientific paper. My Python project consists of a few different files (modules) and also some classes. How do you illustrate this in a UML component diagram? Do i have to use different connectors depending on the "types" of the "components"?

Let's say there are the following 'components':

1. Service (class)
2. PdfCreator (class)
3. calc_utils (module)

1 . interacts with 2. and 3.

Answer 1

Basically a Python class corresponds to a UML class. A Python module can just be seen as UML component containg a set of classes. You are free to show the contained classes and/or to show interfaces with the component. Probably for Python the latter is less appropriate. You can use dependency from a class to show that it needs a module. Here you can especially utilitze «use» relations.
