Solve the following python programming problem given the following code:
def check_star_assume_role_policy(self, iamrole_item) : 
    '
        alert when an IAM Role has an assume_role_policy_document but using a star
        instead of limiting the assume to a specific IAM Role.
        ' 
    tag = '{0} allows assume-role from anyone'.format (self.i_am_singular) 
    def check_statement(statement) : 
        action = statement.get ('Action', None) 
        if (action and (action == 'sts:AssumeRole')) : 
            effect = statement.get ('Effect', None) 
            if (effect and (effect == 'Allow')) : 
                principal = statement.get ('Principal', None) 
                if (not principal) : 
                    return 
if (type (principal) is dict) : 
                    aws = principal.get ('AWS', None) 
                    if (aws and (aws == '*')) : 
                        self.add_issue (10, tag, iamrole_item, notes = json.dumps (statement)) 
else : 
                    if (aws and (type (aws) is list)) : 
                        for entry in aws : 
                            if (entry == '*') : 
                                self.add_issue (10, tag, iamrole_item, notes = json.dumps (statement))
