#     if i%3==0:

#         l.append(i)

    #----- You can write in one line

    #-----  list Comprehension

l = [i for i in range(100) if i%3==0]

# print(l)

    #------ Dictionary comprehension

d = {i:f"item{i}" for i in range(5)}

        # It will print item than print i(means )

d2 = { value:key for key,value in d.items()}

# print(d,"\n\nAfter changing key,value to value key\n\n",d2)

        #------ Set Comprehension

dress = { dress for dress in ["dress1","dress2","dress2"]}

# print(dress)

even = (i for i in range(10) if i%2==0)
