# lst = ["a","b","c"]
# for rtyu in lst:
#     print(rtyu)
    # here rtyu are just random words.

# very important thing about lists.try the below code
list1 = [1,5,2,8,3,9,4]
list_sorted = list1.sort()
print(list_sorted)
# it will give none as output..but printing the below code will work
list1 = [1,5,2,8,3,9,4]
list1.sort()
print(list1)
# this is because list.sort() function changes the original list without returning anyhtinhg.

# adding anything in lists. use of append
list1.append(34)

# to find sum of numbers in a list
l1=[34,45,76]
print(l1[0]+l1[1]+l1[2])
print(sum(l1))
