Python | List of different zipper sizes

Michael Zippo

Method # 1: Using enumerate () + loop
This is the way we use brute force to accomplish this particular task. In this process, we loop through both lists, and when one becomes larger than the other, we loop through the elements to start over from the beginning.

       # Python3 demo code  
  # archive of two different list sizes  
  # using enumerate () + loop  
   
  # initializing lists  
   test_list1   =   [  7  ,   8  ,   4  ,   5  ,   9  ,   10  ] 
   test_list2   =   [   1  ,   5  ,   6  ] 
   
  # printing original lists  
   print   (  "The original list 1 is:"   +   str   (test_list1)) 
   print   (  "The original list 2 is:"   +   str   (test_list2)) 
   
  # using enumerate () + loop  
  # archive of two different list sizes  
   res   =   [] 
   for   i, j   in   enumerate   (test_list1): 
     res.append ((j, test_list2 [i  %   len   (test_list2)])) 
   
  # print result  
   print   ( " The zipped list is: "  +   str   (res ))

Exit:

 The original list 1 is: [7, 8, 4, 5, 9, 10] The original list 2 is : [1, 5, 6] The zipped list is: [(7, 1), (8, 5), (4, 6), (5, 1), (9, 5), (10, 6)]

Method # 2: Using itertools.cycle()
This is another way to accomplish this particular task: in this loop we shorten the list so that it can start over from the beginning in case the smaller list is exhausted using the zip function.

Exit:

 The original list 1 is: [7, 8, 4, 5, 9, 10] The original list 2 is: [1, 5, 6] The zipped list is: [(7, 1), (8, 5), (4, 6), (5, 1), (9, 5), (10, 6)]
