Given list1= [1, 2, 3, 4, 5] Write either a for loop or while loop to create a new list, named pair_list, to include all the combinations of 2 elements from list1, i.e., [[1, 2], [1, 3], [1, 4], [1, 5], [2, 3], [2, 4], [2, 5], [3, 4], [3, 5], [4, 5]]. Hint: use nested loops: 1. the outer loop steps through list items. 2. at each iteration of the outer loop, the inner loop iterates over the subsequence following the current item of the outer loop. 3. the major difficulty arises from constructing the sequence to be iterated over every time when the inner loop is triggered. At the 1st iteration of the outer loop, the sequence to be iterated over for the inner loop is [2, 3, 4, 5]; at the 2nd iteration, it is [3, 4, 5]; and so on. 4. if you attempt to implement the task with a for loop, think about using enumerate() to generate the index of the current item being processed by the outer iteration, and use it in slicing to construct the iterable used by the inner loop. 5. if you attempt to implement the task with a while loop, you need 2 counter variables, one used as the index for the outer loop and the other for the inner loop.
