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))

Output:

True
