Question

Complete the following class definition, Box, for representing cardboard boxes with given dimensions, width-by-height-by-depth, that can hold a number of objects weighing, in total, up to the specified max Weight. Write in the code for the two incomplete methods: addObject and isLargerThan class Box: def --_init_-- (self, width, height, depth, maxWeight): self.width = width self.height = height self.depth = depth self.maxWeight = maxWeight self.objectsInside = [] self.currentWeightInside = 0 self.currentNumberOfObjectsInside = 0 def volume(self): return self.width * self.height * self.depth def numberofObjectsInside(self): return self.currentNumberOfObjectsInside def reinainingWeightCapacity(self): return self.maxWeight - self.currentWeightInside # If the box's weight capacity will not be exceeded, # add given object to the box, updating objectsInside, # currentWeightInside and currentNumberOfObjectsInside # Otherwise, print an appropriate message. # def addObject(self, object, objectWeight): ??? # Return False if the size (by volume) of self is larger than that of the other box # Return False otherwise. # def isLargerThan(self, otherBox): ???

Explanation / Answer

Here is the modified code for you:

#!/usr/bin/python
class Box:
   def __init__(self, width, height, depth, maxWeight):
       self.width = width
       self.height = height
       self.depth = depth
       self.maxWeight = maxWeight
      
       self.objectsInside = []
       self.currentWeightInside = 0
       self.currentNumberOfObjectsInside = 0
  
   def volume(self):
       return self.width * self.height * self.depth
   def numOfObjectsInside(self):
       return self.currentNumberOfObjectsInside
   def remainingWeightCapacity(self):
       return self.maxWeight - self.currentWeightinside
      
   def addObject(self, object, objectWeight):
       if remainingWeightCapacity >= objectWeight:
           self.objectsInside.append(object)
           self.currentWeightInside = self.currentWeightinside + objectWeight
           self.currentNumberOfObjectsInside = self.currentNumberOfObjectsInside + 1
       else:
           print 'Adding this object will exceed box capacity.'
   def isLargerThan(self, otherBox):
       if self.volume() > otherBox.volume():
           return True
       return False
