Import from Module by Importing via String in Python – How to

python

I know I can use importlib to import modules via a string. How can I recreate the import * functionality using this library? Basically, I want something like this:

importlib.import_module('path.to.module', '*')

My reasons for not name-spacing the imported attributes are deliberate.

Here is a solution: import the module, then one by one make alias in the current namespace:

import importlib

# Import the module
mod = importlib.import_module('collections')

# Determine a list of names to copy to the current name space
names = getattr(mod, '__all__', [n for n in dir(mod) if not n.startswith('_')])

# Copy those names into the current name space
g = globals()
for name in names:
    g[name] = getattr(mod, name)

The only way I found:

module = __import__(module, globals(), locals(), ['*'])
for k in dir(module):
    locals()[k] = getattr(module, k)

see https://docs.python.org/2/tutorial/modules.html

In section 6.4.2. Intra-package References:

If the import module in the same dir, use e.g: from . import core
If the import module in the top dir, use e.g: from .. import core
If the import module in the other subdir, use e.g: from ..other import core

Note: Starting with Python 2.5, in addition to the implicit relative imports, you can write explicit relative imports with the from module import name form of import statement. These explicit relative imports use leading dots to indicate the current and parent packages involved in the relative import. From the surround module.
