To merge two dictionaries in Python, you can use the update() method or the ** operator.
Option 1: Using the update() method:
dict1 = {'a': 1, 'b': 2}
dict2 = {'c': 3, 'd': 4}
dict1.update(dict2)
print(dict1)
Output:
{'a': 1, 'b': 2, 'c': 3, 'd': 4}
In this method, the update() method adds the key-value pairs from dict2 into dict1. If there are any common keys, the corresponding values in dict1 will be updated with the values from dict2.
Option 2: Using the ** operator:
dict1 = {'a': 1, 'b': 2}
dict2 = {'c': 3, 'd': 4}
merged_dict = {**dict1, **dict2}
print(merged_dict)
Output:
{'a': 1, 'b': 2, 'c': 3, 'd': 4}
In this method, the ** operator unpacks the key-value pairs from both dictionaries and creates a new dictionary with those pairs. If there are any common keys, the corresponding values from the second dictionary (dict2) will overwrite the values from the first dictionary (dict1).
Either method can be used to merge dictionaries in Python, choose the one that suits your needs and coding style.
