import whole list using import once

Question

how do I achieve this,

imports = 'tensorflow torch requests re keyword builtins enum sys functools operator os itertools collections'.split()

import *imports

or

import imports

both fail

Is this a purely academical question or do you intend to use this in production code? — user8408080, Apr 16 '22 at 23:27
Why do you want to import only once? Why not follow standard practice and use multiple import statements? — wjandrea, Apr 16 '22 at 23:39

This seems strange, but you can achieve that by using exec()

exec(f"import {', '.join(imports)}")

Bear in mind that usage of exec() with users input is insecure

Actually there are two ways I can point:

Using import_module function from importlib, the problem with this method is it will import the module and will store it in as a object, so you can use a variable to get the values, but can't call the module directly in code.

from importlib import import_module
imports = 'tensorflow torch requests re keyword builtins enum sys functools operator os itertools collections'.split()

modules = [import_module(lib) for lib in imports]

Using exec, it's equivalent to call the imports in your code, and you'll be able to do the call of module functions, classes etc.

imports = 'tensorflow torch requests re keyword builtins enum sys functools operator os itertools collections'.split()

for module in imports:
    exec(f'import {module}')

import whole list using import once
