Python:从导入的模块中获取导入模块的详细信息

我想要的是:

mod1:

from mod2 import f
f(...)

mod2:

from things_i_want import parent_module, importing_module
def f(*args, **kwargs):
    from importing_module.parent_module import models
    # ... do some stuff with it, including populating v with a string

    v = 'some_string'
    m = getattr(importing_module, v, None)
    if callable(m)
        return m(*args, **kwargs)

我丑陋的解决方法:

mod1:

from mod2 import f as _f
def f(*a, **k):return _f(__name__, globals(), *a, **k)
f(...)

def f(module_name, globs, *args, **kwargs):
    # find parent modules path
    parent_module_path = module_name.split('.')[0:-1]
    # find models modules path
    models_path = parent_module_path + ['models',]
    # import it
    models = __import__('.'.join(models_path), {}, {}, [''])
    # ... do some stuff with it, including populating v with a string

    v = 'some_string'
    if v in globs:
        return globs[v](*args, **kwargs)
