仅导入模块的某些部分，但将这些部分列为字符串

Question

This question was marked as duplicate . However the duplicate questions deals with modules while my question is asking for how to import parts of module.

I know that I can import certain portions of the module by using from mymodule import myfunction . What if want to import several things, but I need to list them as strings. For example:

import_things = ['thing1', 'thing2', 'thing2']
from mymodule import import_things

I did ask this question , but it looks like I need to use the trick (if there is one) above for my code as well.

Any help is appreciated.

Answer 1

import importlib

base_module = importlib.import_module('mymodule')
imported_things = {thing: getattr(base_module, thing) for thing in import_things}

imported_things['thing1']() # Function call

If you want to be able to use the things which have been imported globally, then do:

globals().update(imported_things)
thing1() # function call

To remove the imports, you can do

del thing1

or

del globals()['thing1']

Another useful operation you can do is to reload a module
