Python: Use multiple map arguments

Python map: Exercise-7 with Solution

Write a Python program to add two given lists and find the difference between lists. Use map() function.

Sample Solution:

Python Code :

def addition_subtrction(x, y):
    return x + y, x - y
 
nums1 = [6, 5, 3, 9]
nums2 = [0, 1, 7, 7]
print("Original lists:")
print(nums1)
print(nums2)
result = map(addition_subtrction, nums1, nums2)
print("\nResult:")
print(list(result))

Sample Output:

Original lists:
[6, 5, 3, 9]
[0, 1, 7, 7]

Result:
[(6, 6), (6, 4), (10, -4), (16, 2)]

Example:

# How to merge two dictionaries
# in Python 3.5+

x = {'p': 1, 'q': 3}
y = {'q': 5, 'r': 8}

z = {**x, **y}

z
{'r': 4, 'p': 1, 'q': 3}

z = dict(x, **y)
print(z)
