Class accepts varying arguments Python -

how class take varying arguments? example, if had class this

class shape(object): def __init__(self, sides): self.sides = sides

if phone call shapes(3), sides 3 aka triangle.

how this: if wanted phone call shape() no arguments, automatically create shape() have self.sides = 4. aka square

make default argument:

class shape(object): def __init__(self, sides=4): self.sides = sides
