Python: Find the difference between consecutive numbers in a given list
Python List: Exercise - 104 with Solution
Write a Python program to find the difference between consecutive numbers in a given list.
Sample Solution:
Python Code:
def diff_consecutive_nums(nums):
result = [b-a for a, b in zip(nums[:-1], nums[1:])]
return result
nums1 = [1, 1, 3, 4, 4, 5, 6, 7]
print("Original list:")
print(nums1)
print("Difference between consecutive numbers of the said list:")
print(diff_consecutive_nums(nums1))
nums2 = [4, 5, 8, 9, 6, 10]
print("\nOriginal list:")
print(nums2)
print("Difference between consecutive numbers of the said list:")
print(diff_consecutive_nums(nums2))
Sample Output:
Original list: [1, 1, 3, 4, 4, 5, 6, 7] Difference between consecutive numbers of the said list: [0, 2, 1, 0, 1, 1, 1] Original list: [4, 5, 8, 9, 6, 10] Difference between consecutive numbers of the said list: [1, 3, 1, -3, 4]

Python: Tips of the Day
Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:
Example:
def tips_check_prop(fn, prop): return lambda obj: fn(obj[prop]) check_age = tips_check_prop(lambda x: x >= 25, 'age') user = {'name': 'Owen', 'age': 25} print(check_age(user))
