I am trying to learn currying in Python for my class and I have to overload the () operator for it. However, I do not understand how can I can go about overloading the () operator. Can you explain the logic behind overloading the parentheses? Should I overload first ( and then ) or can I do any of these? Also, is there special name for parentheses operator?
You can make an object callable by implementing the __call__
method:
class FunctionLike(object):
def __call__(self, a):
print("I got called with {!r}!".format(a))
fn = FunctionLike()
fn(10)
# --> I got called with 10!
