@ioistired

here is a sample method that pretty prints a SubclassNode:

def pformat(self, _indent_level=1): out = '{0.module}.{0.qualname}'.format(self.cls)

for child in self.children:
    out += '\n' + '\t' * _indent_level + child.pformat(_indent_level+1)

return out

class A: pass class B(A): pass class C(A): pass class D(B, C): pass class E(A): pass class F(B): pass print(inspect.getsubclasstree(A).pformat()) main.A main.B main.D main.F main.C main.D main.E
