Python: Zip two given lists of lists
Python List: Exercise - 89 with Solution
Write a Python program to Zip two given lists of lists.
Sample Solution:
Python Code:
list1 = [[1, 3], [5, 7], [9, 11]]
list2 = [[2, 4], [6, 8], [10, 12, 14]]
print("Original lists:")
print(list1)
print(list2)
result = list(map(list.__add__, list1, list2))
print("\nZipped list:\n" + str(result))
Sample Output:
Original lists: [[1, 3], [5, 7], [9, 11]] [[2, 4], [6, 8], [10, 12, 14]] Zipped list: [[1, 3, 2, 4], [5, 7, 6, 8], [9, 11, 10, 12, 14]]

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))
