#unpacking tuple
left = 10
right = 11
print "left= ",left 
print" right= ",right
left,right = right,left

print "left= ",left 
print" right= ",right
fruit={'Guava','Orange','Mango'}
vegetable={'Bottle gourd','Cucumber','Carrot'}
#Symmetric_difference() and " ^" operator
s1={1,2,3}
s2={4,5,6}
p=[7,8,9]
s=s1.symmetric_difference(s2)
s5=s1.symmetric_difference(p)
s3=s1^s2
#s4=s1^p
print(s)
print(s3)
#print(s4)
print(s5)
#set comprehension
lowFruit={item.lower() for item in fruit if item != 'Mango'}
lowFruit2=set(map(lambda item: item.lower(),fruit))
print(lowFruit)
print(lowFruit2)
