Python: Iterate over all pairs of consecutive items in a given list
Python List: Exercise - 135 with Solution
Write a Python program to iterate over all pairs of consecutive items in a given list.
def pairwise(l1): temp =  for i in range(len(l1) - 1): current_element, next_element = l1[i], l1[i + 1] x = (current_element, next_element) temp.append(x) return temp l1 = [1,1,2,3,3,4,4,5] print("Original lists:") print(l1) print("\nIterate over all pairs of consecutive items of the said list:") print(pairwise(l1))
Original lists: [1, 1, 2, 3, 3, 4, 4, 5] Iterate over all pairs of consecutive items of the said list: [(1, 1), (1, 2), (2, 3), (3, 3), (3, 4), (4, 4), (4, 5)]

When we speak of division we normally mean (/) float division operator, this will give a precise result in float format with decimals.
For a rounded integer result there is (//) floor division operator in Python. Floor division will only give integer results that are round numbers.
print(1000 // 300) print(1000 / 300)
