Question 15

Write a program to compare two equal sized lists and print the first index where they differ.

Solution
print("Enter two equal sized lists")
l1 = eval(input("Enter first list: "))
l2 = eval(input("Enter second list: "))

for i in range(len(l1)):
    if l1[i] != l2[i]:
        print("Lists differ at index", i)
        break;
else:
    print("Lists are equal")
Output
Enter two equal sized lists
Enter first list: [80, 60, 50, 40, 30]
Enter second list: [80, 60, 55, 42, 30]
Lists differ at index 2

=====================================

Enter two equal sized lists
Enter first list: [80, 60, 50, 40, 30]
Enter second list: [80, 60, 50, 40, 30]
Lists are equal
Answer

l1
=
eval
(
input

Output
Enter two equal sized lists
Enter first list: [80, 60, 50, 40, 30]
Enter second list: [80, 60, 55, 42, 30]
Lists differ at index 2
