The merge operator is a new feature in Python 3.9 that allows you to “merge two dictionaries”. The syntax of the merge operator is a “pipe character (|)”.
Syntax
dict1 | dict2Operands
- dict1: Current dictionary object
- dict2: Another dictionary object
Return value
It returns the merged dictionary as a dict instance. The “merge operator” creates a new dictionary containing both dictionaries’ keys and values. If there are duplicate keys, the value from the right-hand dictionary will be used.
Example: How to Use Merge Operator in Python
dict1 = {'a': 1, 'b': 2}
dict2 = {'c': 3, 'd': 4}
new_dict = dict1 | dict2
print(new_dict)Output
{'a': 1, 'b': 2, 'c': 3, 'd': 4}
The “merge operator” is a convenient way to merge two dictionaries. It is shorter, more concise than the “dictionary.update()” method, and more readable.
