Question

rod1 and rod2 are instances of the Length class. Attributes start_val and end_val of both rod1 and rod2 are read from input. In the Length class, define instance method compute_length() with self as the parameter to return the value of attributes end_val minus start_val.

1 class Length:
definit__(self):

self.start val = 0
self.end_val = 0
