Python Program to Merge Two Dictionaries

 dict_1 = {1: 'a', 2: 'b'}

dict_2 = {2: 'c', 4: 'd'}

print(dict_1|dict_2)

Output

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

Example 2: Using operator **

dict_1 = {1: 'a', 2: 'b'}

dict_2 = {2: 'c', 4: 'd'}

print({**dict_1, **dict_2})

Output

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

Example 3: Using copy() and update()

dict_1 = {1: 'a', 2: 'b'}

dict_2 = {2: 'c', 4: 'd'}

dict_3 = dict_2.copy()

dict_3.update(dict_1)

print(dict_3)

Output

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