Generic 3 - Answer All Question

Find the error in the following program to get the given output?
class Fruits:
def init(self, f1, f2):
self.f1=f1
self.f2=f2
def display(self):
print("Fruit 1 = %s, Fruit 2 = %s" %(self.f1, self.f2))
F = Fruits ('Apple', 'Mango')
del F.display
F.display()
Output
Fruit 1 = Apple, Fruit 2 = Mango

Write the output of the (allowing program.
class Sample:
num=0
def _init_(self, var):
Sample.num+=1
self. var=var
print("The object value is= ", var)
print("The count of object created Sample.num)
= ",
S1=Sample(15)
S2=Sample(35)
S3=Sample( 45)
