这是我迄今为止发现的最好的方法:

from os.path import dirname, join, isdir, abspath, basename
from glob import glob
pwd = dirname(__file__)
for x in glob(join(pwd, '*.py')):
    if not x.startswith('__'):
        __import__(basename(x)[:-3], globals(), locals())

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.

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

何时从。Import *不够好，这是对ted的回答的改进。具体来说，这种方法不需要使用__all__。

"""Import all modules that exist in the current directory."""
# Ref https://stackoverflow.com/a/60861023/
from importlib import import_module
from pathlib import Path

for f in Path(__file__).parent.glob("*.py"):
    module_name = f.stem
    if (not module_name.startswith("_")) and (module_name not in globals()):
        import_module(f".{module_name}", __package__)
    del f, module_name
del import_module, Path

请注意，globals()中没有module_name是为了避免在已经导入模块时重新导入模块，因为这可能存在循环导入的风险。

使用importlib，唯一需要添加的是

from importlib import import_module
from pathlib import Path

__all__ = [
    import_module(f".{f.stem}", __package__)
    for f in Path(__file__).parent.glob("*.py")
    if "__" not in f.stem
]
del import_module, Path

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。
