How is a mutable object different from an immutable object in Python ?

Identify one mutable object and one immutable object from the following:

(1, 2), [1, 2], {1:1, 2:2}, '123'

Give two examples of each of the following:

1. Arithmetic operators
2. Relational operators

Identify the correct output(s) of the following code. Also write the minimum and the maximum possible values of the variable b.

import random
a = "Wisdom"
b = random.randint(1, 6)
for i in range(0, b, 2):
    print(a[i], end = '#')

1. W#
2. W#i#
3. W#s#
4. W#i#s#

The code provided below is intended to swap the first and last elements of a given tuple. However, there are syntax and logical errors in the code. Rewrite it after removing all errors. Underline all the corrections made.

def swap_first_last(tup)
    if len(tup) < 2:
    return tup
    new_tup = (tup[-1],) + tup[1:-1] + (tup[0])
    return new_tup

result = swap_first_last((1, 2, 3, 4))
print("Swapped tuple: " result)
