使用Python包将子包中的类导入主命名空间

Question

I'm trying to re-organise my code-base into a proper Python package (with subpackages) ready for uploading to PyPI. I have the following directories (for testing):

Py6S/
    __init__.py
    test.py
    Params/
          __init__.py
          AeroModel.py

AeroModel.py contains:

class AeroModel:
    NO_AEROSOL=0
    CONTINENTAL=1
    MARITIME=2
    URBAN=3
    USER=4
    DESERT=5
    BIOMASS_BURNING=6
    STRATOSPHERIC=7

The Py6S init .py contains:

__all__ = ["Params"]

The Params init .py contains:

__all__ = ["AtmosModel", "AeroModel", "AtmosCorr"]

However, when I do from Py6S import * I get Params available to reference, but not AtmosModel or AeroModel.

I want to be able to type from Py6S import * and get all of AeroModel, AtmosModel, AtmosCorr etc available to use without having to put any module names in front of them.

Answer 1

if Py6S's __init__.py has from Params import * : you'd need to do:

import Params
__all__ = ["Params"]
from Params import *
__all__ += Params.__all__

to add those to Py6S's __all__
