避免方法中过多的参数

Question

I would like to know if there is a way to avoid to pass too many arguments to a method, currently I am passing 5, which I consider would make the code harder to maintain and less clean. In this case the method generic_column. Currently passes 5 arguments but it might pass 8 or more.

class BranchBuilder(object):
    """docstring forBranchBuilder."""
    def __init__(self, raw):
        self.raw = raw

    @staticmethod
    def generic_column(size, posx, distance, raw=True,
                       color="red", complex=True):
        """Build the column according the needed requirements."""
    # creates column with arguments.
        return generic_column

    def builder(self):
        """Build the branch that contains all the columns."""
        initial_column = self.generic_column(3, 120, 66, raw=True,
                                             color="white", complex=False)
        mid_column = self.generic_column(3, 120, 66, raw=False, color="black",
                                         complex=False)
        last_column = self.generic_column(3, 120, 66, raw=False, complex=True)

I would like to found a way to make it easier to maintain and clear to any other person who has to deal with the code ahead.

Why not **kwargs :

def generic_column(**kwargs):
    """Build the column according the needed requirements."""
# creates column with arguments.
    return generic_column
