How to concatenate Python dictionaries?

In Python, combining dictionaries can be done using the update() method or by using the syntax {**dict1, **dict2}.

Here is an example of using the update() method to concatenate dictionaries:

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

dict1.update(dict2)
print(dict1)

Output:

{'a': 1, 'b': 2, 'c': 3, 'd': 4}

Another way is to use the syntax {**dict1, **dict2}.

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

dict3 = {**dict1, **dict2}
print(dict3)

Output: indicate/represent/express/reflect

{'a': 1, 'b': 2, 'c': 3, 'd': 4}

Both of these methods can combine two dictionaries into a new dictionary.
