You can use the sorted() function in combination with the key argument to sort a list of dictionaries by a specific key. Here is an example:
# List of dictionaries
data = [
{'name': 'John', 'age': 25},
{'name': 'Sarah', 'age': 20},
{'name': 'Mike', 'age': 30},
]
# Sort the list by the 'age' key in ascending order
sorted_data = sorted(data, key=lambda x: x['age'])
# Print the sorted list
for item in sorted_data:
print(item)
Output:
{'name': 'Sarah', 'age': 20}
{'name': 'John', 'age': 25}
{'name': 'Mike', 'age': 30}
In this example, the key argument in the sorted() function is set to lambda x: x['age'], which specifies that the sorting should be based on the value of the 'age' key in each dictionary. The resulting list, sorted_data, will contain the dictionaries sorted by the 'age' key in ascending order.
