Describe how the dictionary merge (|) operator introduced in Python 3.9 simplifies merging dictionaries.

 The dictionary merge (|) operator introduced in Python 3.9 provides a concise, readable way to combine two dictionaries by returning a new merged dictionary. It replaces values from the right operand if keys overlap, simplifying previous, verbose merging methods.

The (|) operator merges dictionaries, creating a new one without modifying originals, making code cleaner and easier to chain multiple merges. It simplifies the process of combining dictionaries, especially when order and key conflicts matter.

Code

dict1 = {'a': 1, 'b': 2}
dict2 = {'b': 3, 'c': 4}

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