How can I merge two nested dictionaries in Python?

You can use a recursive function to merge nested dictionaries. Would you like to see an example?

Yes, please provide an example of merging two nested dictionaries.

Here's a simple example:

def merge_dicts(dict1, dict2):
    for key, value in dict2.items():
        if key in dict1 and isinstance(dict1[key], dict) and isinstance(value, dict):
            merge_dicts(dict1[key], value)
        else:
            dict1[key] = value
    return dict1

# Example usage:
dict1 = {'a': 1, 'b': {'c': 2}}
dict2 = {'b': {'d': 3}, 'e': 4}
merged = merge_dicts(dict1, dict2)
print(merged)

This will merge dict2 into dict1.

What will the output be for that example?

The output will be: {'a': 1, 'b': {'c': 2, 'd': 3}, 'e': 4}. It combines the nested values.
