Python: Add three lists using map function and lambda

Python map: Exercise-2 with Solution

Write a Python program to add three given lists using Python map and lambda.

Sample Solution:

Python Code :

nums1 = [1, 2, 3] 
nums2 = [4, 5, 6] 
nums3 = [7, 8, 9] 
print("Original list: ")
print(nums1)  
print(nums2)  
print(nums3)  
result = map(lambda x, y, z: x + y + z, nums1, nums2, nums3) 
print("\nNew list after adding above three lists:")
print(list(result))

Sample Output:

Original list: 
[1, 2, 3]
[4, 5, 6]
[7, 8, 9]

New list after adding above three lists:
[12, 15, 18]

Python: Tips of the Day

Returns the symmetric difference between two iterables, without filtering out duplicate values:

Example:

def tips_symmetric_difference(p, q):
  _p, _q = set(p), set(q)
  return [item for item in p if item not in _q] + [item for item in q if item not in _p]
print(tips_symmetric_difference([2, 4, 6], [2, 4, 8]))

Output:

[6, 8]
