Get a list of class variables

Check the code below:

class Base:
    def __init__(self, name, age):
        self.name = name
        self.age = 0
        
if __name__ == "__main__":
    object = Base("Person Name")
    print (object.name)

I can access all the class variables using them with object name. 

But i need a list of all the class variables, because in my real world program, I am not having a full access to the base code, so i need a list of all the class variables.

Hope I have conveyed my concern correctly.
