Passing stored arguments to a python class

I want to write a program that runs multiple classes. My code looks like

list_of_classes = [class1, class2, class3]

def run_class(class_):
    print("Running class ", class_.__name__) #All my classes have such attribute
    x = class_()
    x.doStuff()
    #etc

for class_ in list_of_classes:
    run_class(class_)

Problem is, that for some classes, I want to pass some arguments (which are optional). For example, let's assume that for class1 I want to pass the argument iterations = 150.

How do I do that? My first thought is to change the list_of_classes like so:

list_of_classes = [(class1, 'iterations=150'), (class2, ''), (class3, '')]

But how do I pass the second part of the tuple as argument?

I do not want to place the arguments directly in the list like so:

list_of_classes = [class1(iterations=150),class2,class3]

because I will not be able to use the __name__ attribute in my function.

You can try:

list_of_classes = [
    (class1, [], {'iterations': 150}),
    (class2, [], {}),
    (class3, [], {}),
]
for class_, args, kwargs in list_of_classes:
    run_class(class_, *args, **kwargs)
