size=int(input("Enter the size of List:"))
li=[]
print("Enter Elements in list:")
for i in range(0,size):
    print((i+1),end=": ")
    li.append(int(input()))
count=0
#Print Given Elements
print("Elements in given List:")
print(li)
#counting the odd elements and
# changing value to "a"
#so that we can remove them easily afterwards

        count=count+1
        li[i]="a"

for i in range(0,count):
    li.remove("a")

# you can also replace from line 14 to line 20 with
# li=[ele for ele in li if(ele%2==0)]
# it will do the same thing.
print("List after deleting odd element:")
print(li)
