[issue or Question]: "How can I efficiently sort a list of dictionaries by a specific key?" [programming language]: "Python" Output: To efficiently sort a list of dictionaries by a specific key in Python, you can use the sorted() function with a custom key function or lambda function. Here's a step-by-step explanation and example: 1- Use the sorted() function: The sorted() function in Python can sort any iterable, including lists. It accepts an optional key parameter, which allows you to specify a function to be called on each element prior to making comparisons. 2- Define a custom key function or lambda function: This function extracts the value of the specific key from each dictionary in the list. This key function is then used by sorted() to determine the sorting order. Here's an example: # Sample list of dictionaries data = [ {'name': 'John', 'age': 30}, {'name': 'Alice', 'age': 25}, {'name': 'Bob', 'age': 35} ] # Sort the list of dictionaries by the 'age' key sorted_data = sorted(data, key=lambda x: x['age']) # Print the sorted list for item in sorted_data: print(item) In this example, lambda x: x['age'] is a lambda function that extracts the value of the 'age' key from each dictionary (x) in the list. The sorted() function then sorts the list of dictionaries based on these extracted age values. You can replace 'age' with any other key you want to sort the list of dictionaries by. This approach ensures efficient sorting of the list of dictionaries based on the specified key.
