and it can be automatically assign to the function object with this snippet

for f in globals():
    if not hasattr(globals()[f], '__call__'):
        continue

        meta = json.loads(globals()[f].__doc__)
    except:
        continue
    for k, v in meta.items():
        setattr(globals()[f], k, v)
