How do I concatenate dicts in Python in pure Python?

In Python, you can concatenate dictionaries using various methods, including the `update()` method, dictionary unpacking, or a dictionary comprehension. Here are some examples illustrating these methods.

Keywords: dictionary, concatenate, Python, update, unpacking, comprehension
Description: This content provides methods to concatenate dictionaries in Python using simple and effective techniques.
# Example 1: 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 2: Using dictionary unpacking (Python 3.5+) dict1 = {'a': 1, 'b': 2} dict2 = {'b': 3, 'c': 4} combined = {**dict1, **dict2} print(combined) # Output: {'a': 1, 'b': 3, 'c': 4} # Example 3: Using dictionary comprehension dict1 = {'a': 1, 'b': 2} dict2 = {'b': 3, 'c': 4} combined = {k: v for d in [dict1, dict2] for k, v in d.items()} print(combined) # Output: {'a': 1, 'b': 3, 'c': 4}
