Question

What will be the output of the following statements?
i. list1 = [12,32,65,26,80,10]
list1.sort()
print(list1)
ii. list1 = [12,32,65,26,80,10]
sorted(list1)
print(list1)
iii.list1 = [1,2,3,4,5,6,7,8,9,10]
list1[::-2]
list1[:3] + list1[3:]
iv.list1 = [1,2,3,4,5]
list1[len(list1)-1]

Answer 1

Answer:

i) The sort() method will sort the list in ascending order in place.

OUTPUT:

[10, 12, 26, 32, 65, 80]

ii) The sorted() function takes a list as a parameter and creates a new list consisting of the same elements arranged in sorted order. It doesn’t change the list which is passed as a parameter itself.

OUTPUT:  

[12, 32, 65, 26, 80, 10]

iii) The statement in line 2 has a negative step size. This means that the list will be traversed in reversed order with step size 2.

OUTPUT: [10, 8, 6, 4, 2]

The statement in line 3 will print the complete list. i.e. [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

iv) This will print the last element of the list. i.e. 5  

list1[len(list1)-1]

list1[5-1]

list1[4]

5
