Question

I’d like to know if it is possible to automatically import all subclasses of a class in python without writing import subclassxy for every subclass.

Answer 1

Here is a draft example that can give you idea about what you want to do:

my_module.py

class RootClass(object):
    pass

class ChildClass(RootClass):
    pass

in another file.py

import sys

from my_module import RootClass

# Loop over all subclasses of RootClass.
for class_ in RootClass.__subclasses__():
    # from module import subclass.
    __import__(class_.__module__, globals(), locals(), [class_.__name__,])

    # Update the global namespace with the new class
    globals().update({class_.__name__:
                      getattr(sys.modules[class_.__module__], 
                              class_.__name__)})

print ChildClass
# OutPut : <class 'my_module.ChildClass'>

PS: i don’t advice you to do this !!!!
