How do I merge dicts in Python for beginners?

Merging dictionaries in Python can be done using various methods. Below are some simple examples for beginners to understand how to combine multiple dictionaries into one.

Example: Merging Dictionaries Using the Update Method

dict1 = {'a': 1, 'b': 2} dict2 = {'b': 3, 'c': 4} dict1.update(dict2) print(dict1) # Output: {'a': 1, 'b': 3, 'c': 4}

Example: Merging Dictionaries Using the Pipe (|) Operator (Python 3.9+)

dict1 = {'a': 1, 'b': 2} dict2 = {'b': 3, 'c': 4} merged_dict = dict1 | dict2 print(merged_dict) # Output: {'a': 1, 'b': 3, 'c': 4}

Example: Merging Dictionaries Using Dictionary Comprehension

dict1 = {'a': 1, 'b': 2} dict2 = {'b': 3, 'c': 4} merged_dict = {k: v for d in (dict1, dict2) for k, v in d.items()} print(merged_dict) # Output: {'a': 1, 'b': 3, 'c': 4}
