An example tool for analyzing python class hierarchy statically

analysts.py

import ast

with open("module.py", "r") as f: # we will analysis this file
    data = f.read()

tree = ast.parse(data)

classes = {} # {class: [parents]} 

for i in tree.body:
    if type(i) == ast.ClassDef:
        classes[i.name] = [i.id for i in i.bases] # problem: can't separate classes whose are same names, you may also add path of module for fix this
        # Another problem is class imports from other modules.
      
child_tree = {} # {class: [childs]}

for cls, parents in classes.items():
    for parent in parents:
        child_tree.setdefault(parent, [])
        child_tree[parent].append(cls)
