Python list of dictionaries get value | Example code

To get the value of a list of dictionaries first we have to access the dictionary using indexing.

list_data[index][key]

Example list of dictionaries get value in Python

Simple example code.

data = [{101: 'Any', 102: 'Bob'},
         {103: 'John', 105: 'Tim'}]

# display data of key 101
print(data[0][101])

# display data of key 105
print(data[1][105])

Output:

Access the key:value pairs from the list of dictionaries

We can easily access any key:value pair of the dictionary, just pass the index value of the dictionary in a square bracket [].

data = [{101: 'Any', 102: 'Bob'},
         {103: 'John', 105: 'Tim'}]

print(data[1])

Output:

{103: ‘John’, 105: ‘Tim’}

Get all values of specific key

data = [{'value': 'apple', 'blah': 2},
        {'value': 'banana', 'blah': 3},
        {'value': 'cars', 'blah': 4}]

res = [d['value'] for d in data]

print(res)

Output: [‘apple’, ‘banana’, ‘cars’]

Get all values of the list dictionary

my_dict = [{'value': 'apple', 'blah': 2},
           {'value': 'banana', 'blah': 3},
           {'value': 'cars', 'blah': 4}]

res = []

for key in my_dict:
    for value in key:
        res.append(key.values())

print(res)

Output:

[dict_values(['apple', 2]), dict_values(['apple', 2]), dict_values(['banana', 3]), dict_values(['banana', 3]), dict_values(['cars', 4]), dict_values(['cars', 4])]

To get the value of a specific key in a list of dictionaries in Python, you can use a loop to iterate through the list and access the key you’re interested in for each dictionary. Here’s an example of how to do it:

# Sample list of dictionaries
data = [
    {'name': 'Alice', 'age': 30},
    {'name': 'Bob', 'age': 25},
    {'name': 'Charlie', 'age': 35}
]

# Key you want to access
key_to_access = 'age'

# Iterate through the list of dictionaries and get the value for the specified key
values = [item[key_to_access] for item in data]

# Print the values
for value in values:
    print(value)

In this example, we have a list of dictionaries containing information about people, and we want to access the ‘age’ key for each person. The list comprehension [item[key_to_access] for item in data] is used to extract the values associated with the ‘age’ key from each dictionary in the list.
