Let us write a program to find the length of the list using for loop. Iteration 6: In the sixth iteration, the sixth element of the list L i.e, 5 is assigned to x. Since x is an odd number, x%2==0 evaluates to false. Iteration 1: In the first iteration, the first element of the list L i.e, 0 is assigned to x. Positive index means from left to right and negative index means right to left. Therefore print(x) is not executed. The list objects are mutable i.e, we can change the content of the list. In Python, there is no C style for loop, i.e., for (i=0; i
