Python Merge Dictionaries
Python3 ExamplesGiven two dictionaries, merge them into one dictionary.
Example 1: Using the update() method, the second parameter merges into the first parameter.
def Merge(dict1, dict2):
return(dict2.update(dict1))
# Two dictionaries
dict1 = {'a': 10, 'b': 8}
dict2 = {'d': 6, 'c': 4}
# Returns None
print(Merge(dict1, dict2))
# dict2 is merged into dict1
print(dict2)
Executing the above code produces the following output:
None
{'d': 6, 'c': 4, 'a': 10, 'b': 8}
Example 2: Using **, the function imports parameters in the form of a dictionary.
def Merge(dict1, dict2):
res = {**dict1, **dict2}
return res
# Two dictionaries
dict1 = {'a': 10, 'b': 8}
dict2 = {'d': 6, 'c': 4}
dict3 = Merge(dict1, dict2)
print(dict3)
Executing the above code produces the following output:
{'a': 10, 'b': 8, 'd': 6, 'c': 4}
