## Python Interview Questions 16-20

Let’s start with the 4th set of Python Interview Questions. Mostly, the product-based companies in India ask these questions in the first round of interviews for Business Intelligence Engineer/Data Analyst/Business Analyst/Data Scientist

Python Interview Questions

16. Interchange first and last element in a list

`l = [1,2,3,5,6]temp = l[0]l[0] = l[len(l)-1]l[len(l)-1] = tempprint(l)or l = [4,5,6,7,8]print("List",l)def inter(l):l[0],l[-1] = l[-1],l[0]return l`

print(“Interchanged List” , inter(l))

17. Swap two positions in a list

`p1 = 2p2 = 5l = [1,2,3,4,5,6,7]print("Original List",l)def swap(l,p1,p2):l[p1],l[p2] = l[p2],l[p1]return lprint("Swaped list", swap(l,p1,p2))`

18. To check if a particular element is there in the list

`l = ['a','b','d']count = l.count('d')print(count)or l_set = set(l)if 'b' in l_set:print("Mil gaya")or Use a naive method of loopfor i in range(0,len(l)):if l[i] == 'd':print("Mil gaya at",i)`

19. Get the sum of elements in a list

`l = [1,3,5,6]s = 0for i in range(0,len(l)):s = s+l[i]print(s)or list1 = [9,8,7,6]def sumOfList(list, size):if (size == 0):return 0else:return list[size - 1] + sumOfList(list, size - 1)total = sumOfList(list1, len(list1))print("Sum of all elements in given list: ", total)`

20. Multiple all the numbers in a list

`l = [1,3,5,6]m = 1for i in range(0,len(l)):s = s*l[i]print(s)`
