What s the best way to generate a UML diagram from Python source code

Question

A colleague is looking to generate UML class diagrams from heaps of Python source code   He s primarily interested in the inheritance relationships  and mildly interested in compositional relationships  and doesn t care much about class attributes that are just Python primitives   The source code is pretty straightforward and not tremendously evil--it doesn t do any fancy metaclass magic  for example    It s mostly from the days of Python 1 5 2  with some sprinklings of  modern  2 3ish stuff      What s the best existing solution to recommend

You may have heard of Pylint that helps statically checking Python code  Few people know that it comes with a tool named Pyreverse that draws UML diagrams from the python code it reads  Pyreverse uses graphviz as a backend  It is used like this  pyreverse -o png -p yourpackage    where the   can also be a single file

Certain classes of well-behaved programs may be diagrammable  but in the general case  it can t be done   Python objects can be extended at run time  and objects of any type can be assigned to any instance variable   Figuring out what classes an object can contain pointers to  composition  would require a full understanding of the runtime behavior of the program   Python s metaclass capabilities mean that reasoning about the inheritance structure would also require a full understanding of the runtime behavior of the program   To prove that these are impossible  you argue that if such a UML diagrammer existed  then you could take an arbitrary program  convert  halt  statements into statements that would impact the UML diagram  and use the UML diagrammer to solve the halting problem  which as we know is impossible

Epydoc is a tool to generate API documentation from Python source code  It also generates UML class diagrams  using Graphviz in fancy ways  Here is an example of diagram generated from the source code of Epydoc itself   Because Epydoc performs both object introspection and source parsing it can gather more informations respect to static code analysers such as Doxygen  it can inspect a fair amount of dynamically generated classes and functions  but can also use comments or unassigned strings as a documentation source  e g  for variables and class public attributes
