In python it is called duck typing but you don't need separate
constructors:
def __init__(self, c):
if isinstance(c, int): ...do stuff...
elif isinstance(c, list): ...do stuff...
elif isinstance(c, tuple): ...do stuff...
else:
.
.
.
Remember Python doesn't care what c is and doesn't do
type checking so you can do anything you want.
