Python: Tips of the Day

Merge dictionaries with single line of code

Code: 

x = {
    'a': 1,
    'b': 2
}

y = {
    'c': 3,
    'd': 4
}

z = {
    'e': 5,
    'f': 6
}
print("Original dictionaries:") 
print(x)
print(y)
print(z)
result = dict(**x, **y)
print("\nMerge two dictionary:")
print(result)
result = dict(**x, **y, **z)
print("\nMerge three dictionary:")
print(result)

Output:

Original dictionaries:
{'a': 1, 'b': 2}
{'c': 3, 'd': 4}
{'e': 5, 'f': 6}

Merge two dictionary:
{'a': 1, 'b': 2, 'c': 3, 'd': 4}

Merge three dictionary:
{'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5, 'f': 6}
