Question
![Part 5. Operator Overload:
add
Next, you will add the ability to use the addition operator (+) in conjunction with Simpy objects and floats.
You will implement
add
such that the left-hand side operand of an addition expression can be either a simpy object or a float value
using a Union type. The
add_method should return a new Simpy object and should not mutate the object the method is called on.
When the right-hand side of an addition expression is also a simpy object, you should assert that both objects' values attributes have equal
lengths. Then, you should produce a new simpy object where each item in its values attribute corresponds to the items of the original
Simpy objects at the same index added together. For example:
a = Simpy([1.0, 1.0, 1.0])
b = Simpy([2.0, 3.0, 4.0])
c = a + b
print(c)
# Output: Simpy([3.0, 4.0, 5.0])
When the right-hand side of an addition expression is a float value, you should produce a new simpy object where each item corresponds to
the item at the same index in the left-hand side simpy object added to the float. For example:
a = Simpy( [1.0, 2.0, 3.0])
b = a + 10.0
print (b)
# Output: Simpy([11.0, 12.0, 13.0])
The signature of the
add
function should be:
def_add_(self, rhs: Union[float, Simpy]) -> Simpy:
# This cell tests a Simpy + Simpy
a = Simpy([1.0, 1.0, 1.0])
b = Simpy([2.0, 3.0, 4.0])
C = a + b
print("Actual: ", c, " - Expected: Simpy ([3.0, 4.0, 5.0])")
print("Actual: ", a + a,
- Expected: Simpy([2.0, 2.0, 2.0])")
- Expected: Simpy([4.0, 6.0, 8.0])")
print("Actual: ", b + b,
Python
# This cell tests a Simpy + float
a = Simpy([1.0, 2.0, 3.0])
b 3D а + 10.0
print("Actual: ", b, "
print("Actual:
Expected: Simру ([11.0, 12.0, 13.0])")
Expected: Simpy ([2.0, 3.0, 4.0])")
