  • What is the data type of the variable cheap?
  • What is the data type of the variable r?

  • What is the data type of the variable r.price?

  • For each of the 5 lines in the main code above (annotated #line 1, ..., #line 5), write below the method(s) of class Produce that are used in the execution of that line. If a line does not use (directly or indirectly) a method of class Produce, write N/A.
  • Write the output of the code below
 
class Produce:
def
_init_(self, n, p):
self.name = n
self.price = p
def _str_(self):
return self.name + ': $' + str(self.price)
def _lt__(self, other):
return self.price < other.price
def discount (self, percent):
self.price -= self.price*percent
r = Produce ('rambutan', 20.0) #line 1
d = Produce (' durian', 50.0) #line 2
d.discount (0.50) #line 3
cheap
(r < d) #line 4
print (d) #line 5
