Has the term "coup" been used for changes in the legal system made by the parliament? Python range() is a built-in function available with Python from Python(3. x), and it gives a sequence of numbers based on the start and stop index given. This by default uses 1 as the increment/step value. Python doesn't stop you from doing i = i + 1 inside the loop, but as soon as control goes back to the top of the loop i gets reset to whatever value is next in the sequence. For example, if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[580,400],'sparkbyexamples_com-box-4','ezslot_6',139,'0','0'])};__ez_fad_position('div-gpt-ad-sparkbyexamples_com-box-4-0'); If we want to increment for loop with a specified value we can pass step parameter along with start and stop of range() function.

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. In your example as written i will be reset at each new iteration of the loop (which may seem a little counterintuitive), as seen here: foo_list = To get the output, I have used print (sum). 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.
