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.
Sample Solution:
Python Code:
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))
Sample Output:
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)]

Returns True if the provided function returns True for every element in the list, False otherwise:
Example:
def tips_every(lst, fn=lambda x: x): return all(map(fn, lst)) print(tips_every([2, 4, 3], lambda x: x > 1)) print(tips_every([1, 2, 3]))
