In this article, I have explained the Python range() function and how we can increment the for loop by custom values like 2, 3, etc. Part A: Here's the equivalent for loop that traverses by index: for i in range (len (word)): print (word [i] * n) Part B: Same code using while loop: i = 0 while i < len (word): print (word [i] * n) i += 1. You could use a while loop and increment i based on the condition: while i < (len(foo_list)): print(i) This would be like hopping over the collection.
