Python: Pair up the consecutive elements of a given list

Python List: Exercise - 200 with Solution

Write a Python program to pair up the consecutive elements of a given list.

Sample Solution:

Python Code:

def pair_consecutive_elements(lst):
    result = [[lst[i], lst[i + 1]] for i in range(len(lst) - 1)]
    return result
nums =  [1,2,3,4,5,6]
print("Original lists:")
print(nums)
print("Pair up the consecutive elements of the said list:")
print(pair_consecutive_elements(nums))
nums =  [1,2,3,4,5]
print("\nOriginal lists:")
print(nums)
print("Pair up the consecutive elements of the said list:")
print(pair_consecutive_elements(nums))

Sample Output:

Original lists:
[1, 2, 3, 4, 5, 6]
Pair up the consecutive elements of the said list:
[[1, 2], [2, 3], [3, 4], [4, 5], [5, 6]]

Original lists:
[1, 2, 3, 4, 5]
Pair up the consecutive elements of the said list:
[[1, 2], [2, 3], [3, 4], [4, 5]]
