import and create dynamically an instance of class in python

Question

I would like to import and create dynamically classes in Python.

What I have is a dictionary containing Scikit-learn classifiers such as:

# list_classifiers.py 
AVAILABLE_CLASSIFIERS = {
    "Random Forest Classifier": RandomForestClassifier,
    "KNeighbors Classifier": KNeighborsClassifier
}

What I would like is to import dynamically my classifiers (they are all stored as classes in the directory algorithms) and add it to this dictionary such as:

# list_classifiers.py 
AVAILABLE_CLASSIFIERS = {
    ...,
    "MyOwnClassifier": MyOwnClassifier
}

project
|-- algorithms
     |-- MyOwnClassifier.py
     |-- MyOtherClassifier.py
|-- list_classifiers.py
|-- ...

What I have tried:

# list_classifiers.py 
import importlib
tree = os.listdir('algorithms')
for filename in tree:
    name = filename[:-3]  # remove .py extension to get only the name of the class
    importlib.import_module("project.algorithms."+name)  # sys.modules.keys() contains MyOwnClassifier
    # STRUGGLE GOES HERE: how to add my classes as objects?
    AVAILABLE_CLASSIFIERS[name] = eval(name)  # NameError: name 'MyOwnClassifier' is not defined
    AVAILABLE_CLASSIFIERS[name] = globals()[name]  # KeyError: 'MyOwnClassifier'

Any help will be appreciated,
