Question

What role does the following line of code play in for loops?

max_index = len(words) - 1

Answer 1

Please show more context, as this simply assigns the value equal to length of the words object minus 1 to a variable named max_index.

Answer 2

Rik Gart This line make for loop to go upto the end element in a array because array index starts with 0 and its sizs start with 1 which is always greter than its index so we decrease it by one to reach to end elemnt of an array
