import specific module from the class by different name as string variable

I wanna get a module from a class with different name (string variable). However, the content has same form of string as the original module name.
For example

import timm
model_configs = timm.models.resnet.default_cfgs['resnet34']  #this one works

target_network_root = 'resnet'
model_configs = timm.models.target_network_root.default_cfgs['resnet34']  #this one doesn't work

Since, the target_network_root can change, I might export another network than resnet, I like to call specific module from timm.models as variable. I really appreciate your support.

>Solution :

You can use getattr()

For example:

getattr(timm.models, target_network_root)

=> timm.models.resnet
