Import class from module dynamically

Question

I have class called `'my_class'` placed in `'my_module'`. And I need to import this class. I tried to do it like this: ``` import importlib result = importlib.import_module('my_module.my_class') ``` but it says: ``` ImportError: No module named 'my_module.my_class'; 'my_module' is not a package ``` So. As I can see it works only for modules, but can't handle classes. How can I import a class from a module?

Accepted Answer

It is expecting `my_module` to be a package containing a module named `'my_class'`. If you need to import a class, or an attribute in general, dynamically, just use `getattr` after you import the module:

```
cls = getattr(import_module('my_module'), 'my_class')
```

Also, yes, it does only work with modules. Remember `importlib.import_module` is a wrapper of the internal `importlib.__import__` function. It doesn't offer the same amount of functionality as the full `import` statement which, coupled with `from`, performs an attribute look-up on the imported module.
