I believe you want to find all instances of a specific class.
you could add a simple registry to the class to accomplish this:

    class Parser:
        instance_registry = {}

        def __init__(self, ....):
            """This is the constructor method of class Parser"""
            self.instance_registry[id(self)] = self
            .... other init code ....

        def foo(self): 
            ....

Later you can retrieve a list of all parser instances:

    for parser_id, parser_object in Parser.instance_registry.items():
        do_something_with(parser_object)
