Import * from module by importing via string

Question

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 some

Answer 1

Here is shorten version for @HaiVu answer which refers to this solution from @Bakuriu

import importlib
#import the module
mod = importlib.import_module('collections')
#make the variable global
globals().update(mod.__dict__)

Note:

• This will import lots of things beside the user-defined variables

• @HaiVu solution did the best of it ie. only import user-defined variables

Answer 2

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)
