How do you dynamically load a class in python?
Adding a bit of sophistication to the existing answers.... Show Depending on the use case, it may be somewhat inconvenient to have to explicitly specify the full path (E.g. Let's say I have a python package, like so:
With a command line argument, I can pass an argument that corresponds to a mode that I want to run. I'd like to be able to so something like this:
which outputs:
That works fine, however what we'd REALLY want to get at is this:
Which raises an error:
However, we can add the following to
Then, we can do:
In other worlds, all sub modules/functions/classes we import in init.py will be found directly with importlib.import_module(...), without having to specify the full path from outside.

The file containing these sets of methods and classes is called a module. A module can have other modules inside it. Note: For more information, refer to Python Modules Example: A simple example of importing a module is shown below in which, there are 2 files that are module.py and importing_mod.py in the same directory. The module.py file acts as a module to import_mod.py file. module.py
import_mod.py file
