Merge dictionaries in python

dict_1 = {'John': 15, 'Rick': 10, 'Misa' : 12 }
dict_2 = {'Bonnie': 18,'Rick': 20,'Matt' : 16 }
dict_1.update(dict_2)
print('Updated dictionary:')
print(dict_1)

python Merge Two Dictionaries

dict_1 = {1: 'a', 2: 'b'}
dict_2 = {2: 'c', 4: 'd'}

dict_3 = dict_2.copy()

print(dict_3)

python merge dictionaries

dict1 = {'color': 'blue', 'shape': 'square'}
dict2 = {'color': 'red', 'edges': 4}

dict1.update(dict2) #if a key exists in both, it takes the value of the second dict
# dict1 = {'color': 'red', 'shape': 'square', 'edges': 4}
# dict2 is left unchanged

how to merge two dictionaries

>>> dict_a = {'a': 1, 'b': 2}
>>> dict_b = {'b': 3, 'c': 4}
>>> dict_c = {**dict_a, **dict_b}
>>> dict_c
# {'a': 1, 'b': 3, 'c': 4}

How to merge dictionaries in python

a = {"Kelly": 23, "Derick": 14, "John": 7}
b= {'Ravi': 45, 'Mpho': 67}

             
# combine dictionaries using the merge(|) operator
dict2=a | b
print(dict2)

# Output:
# {'Kelly': 23, 'Derick': 14, 'John': 7, 'Ravi': 45, 'Mpho': 67}

# combine dictionaries using the merge operator
dict3 = {**a, **b}
print(dict3)

# Output:
{'Kelly': 23, 'Derick': 14, 'John': 7, 'Ravi': 45, 'Mpho': 67}

merge two dict python

For dictionaries x and y, their shallowly-merged dictionary z takes values from y, replacing those from x.

In Python 3.9.0 or greater (released 17 October 2020, PEP-584, discussed here):

z = x | y
In Python 3.5 or greater:

z = {**x, **y}
In Python 2, (or 3.4 or lower) write a function:

def merge_two_dicts(x, y):
    z = x.copy()   # start with keys and values of x
    z.update(y)    # modifies z with keys and values of y
    return z
and now:

z = merge_two_dicts(x, y)
