Python is a great language for automating tasks, and one of the things you can automate is the process of importing classes from modules. This can be done using the __import__() function, which takes a string containing the name of the module you want to import, and returns a reference to that module.

To use this function, you first need to figure out the name of the module you want to import. For example, if you want to import the class Foo from the module bar, the name of the module is “bar”. Once you have the name of the module, you can pass it to the __import__() function, and it will return a reference to the module.

Once you have a reference to the module, you can use the dot notation to access the class you want to import. For example, if the module bar contains a class Foo, you can import it by doing the following:

module = __import__(“bar”)

class = getattr(module, “Foo”)

The getattr() function takes two arguments: the first is the reference to the module, and the second is the name of the class you want to import. It will return a reference to the class, which you can then use in your code.

You can also use the __import__() function to import multiple classes from a single module. To do this, you need to pass a list of class names to the __import__() function. For example, if you want to import the classes Foo and Bar from the module baz, you can do it like this:

module = __import__(“baz”)

classes = [“Foo”, “Bar”]

for class_name in classes:

class = getattr(module, class_name)

This will import both the Foo and Bar classes from the baz module. You can then use these classes in your code as usual.

importing classes from modules is a great way to automate tasks in Python. By using the __import__() function, you can import any number of classes from any number of modules, and then use them in your code.
