看看标准库中的pkgutil模块。只要目录中有__init__.py文件，它就会让你做你想做的事情。__init__.py文件可以为空。

import pkgutil
__path__ = pkgutil.extend_path(__path__, __name__)
for imp, module, ispackage in pkgutil.walk_packages(path=__path__, prefix=__name__+'.'):
  __import__(module)

注意你的__init__.py定义了__all__。模块-包文档说

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable, described later. ... The only solution is for the package author to provide an explicit index of the package. The import statement uses the following convention: if a package’s __init__.py code defines a list named __all__, it is taken to be the list of module names that should be imported when from package import * is encountered. It is up to the package author to keep this list up-to-date when a new version of the package is released. Package authors may also decide not to support it, if they don’t see a use for importing * from their package. For example, the file sounds/effects/__init__.py could contain the following code: __all__ = ["echo", "surround", "reverse"] This would mean that from sound.effects import * would import the three named submodules of the sound package.

我已经为此创建了一个模块，它不依赖于__init__.py(或任何其他辅助文件)，并让我只输入以下两行:

import importdir
importdir.do("Foo", globals())

我自己也厌倦了这个问题，所以我写了一个名为automodinit的包来解决它。你可以从http://pypi.python.org/pypi/automodinit/上得到它。

用法是这样的:

将automodinit包包含到setup.py依赖项中。 像这样替换所有__init__.py文件:

__all__ = ["I will get rewritten"]
# Don't modify the line above, or this line!
import automodinit
automodinit.automodinit(__name__, __file__, globals())
del automodinit
# Anything else you want can go after here, it won't get modified.

就是这样!从现在开始导入一个模块将设置__all__为 模块中的.py[co]文件列表，也将导入每个文件 就好像你输入了:

for x in __all__: import x

因此，“from M import *”的效果与“import M”完全匹配。

automodinit从ZIP档案内部运行，因此是ZIP安全的。
