Given code:

# TODO: Create a routine that saves the vector
# <x, y, z> into this Vector3D object.
pass

# TODO: Create a routine that adds this vector with Vector3D other
# and returns the result as a Vector3D object
return None
def __neg__(self):
# TODO: Create a routine that returns the negative (opposite) of
# this vector as a Vector3D object
return None
def __sub__(self, other):
# TODO: Create a routine that subtracts this vector with Vector3D other
# and returns the result as a Vector3D object
return None
def __mul__(self, other):
# TODO: Create a routine that multiplies this vector with other
# depending on its data type, and returns the result as a

# scalar or a Vector3D object.
return None

op = line_in[0].strip()
vec_vals = [int(x) for x in line_in[1:]]
# TODO: a Write routine that processes a line in the input
