I've implemented a test:
class MathOperations:
def __init__(self) -> None:
self._operations = []
def _add_operation(self, operation, other):
self._operations.append(partial(operation, other))
return self
def __add__(self, other):
return self._add_operation(operator.add, other)
def __mul__(self, other):
return self._add_operation(operator.mul, other)
def __sub__(self, other):
return self._add_operation(operator.sub, other)
def __mod__(self, other):
return self._add_operation(operator.mod, other)
def __pow__(self, other):
return self._add_operation(operator.pow, other)
def __call__(self, number):
first_operation, *rest_operations = self._operations
return reduce(
lambda partial_result, operation: operation(partial_result),
rest_operations,
first_operation(number)
)
class _Callable(object):
def __add__(self, other) -> Callable[['_Callable', T1], Callable[[T1], T1]]:
return MathOperations() + other
>>> from lambdas import _
>>> func_one = _ + 1 * 10
>>> func_two = (_ + 1) * 10
>>> func_one(1)
1
>>> func_two(1)
