Thanks for contributing an answer to Stack Overflow! 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. We can loop back to the start by using a control flow statement, i.e., a while statement. To do that, wrap the complete program in a while loop that is always True. Moreover, add a continue statement at a point where you want to start the program from the beginning. You also need to add some code such as a break statement to terminate your program. For example, to increment for loop by 2 in Python you should use the range() with step value 2.if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'sparkbyexamples_com-banner-1','ezslot_19',113,'0','0'])};__ez_fad_position('div-gpt-ad-sparkbyexamples_com-banner-1-0'); In this example, we iterate the list of values using for loop along with the range() and len() functions and display the values from a list by incrementing 2. we can use a while loop in this case.
