Dec 10, 2024 · The easiest way to sort a list by the second element of each sublist is by using the sorted() function with a lambda function as the key. The lambda function lets us specify which element in the sublist to focus on while sorting.

May 22, 2012 · Try using the key keyword argument of sorted(), which sorts in increasing order by default: [('abc', 121), ('abc', 231), ('abc', 148), ('abc', 221)], . key=lambda x: x[1] key should be a function that identifies how to retrieve the comparable element from your data structure. In your case, it is the second element of the tuple, so we access [1].

Feb 18, 2025 · We can specify the sorting key using the key parameter which allows us to sort the tuples based on the second item. Explanation: sorted (a, key=lambda x: x [1]) extract the second element (x [1]) from each tuple for comparison and list is returned in sorted order by the second item of each tuple.

The following sorts list by the first element, then by the second element. You can also sort by one field ascending and another descending for example: sorted_list = sorted(list, key=lambda x: (x[0], -x[1]))

Sort the multi-dimensional array in descending order on the basis of 2 nd column: list_name.sort(key=lambda x:x[1],reverse=True)

Feb 21, 2024 · The example demonstrates the in-place sorting of the given list of lists, using a lambda function that takes each sublist ‘x’ and returns the second element ‘x[1]’ to be used as a key for sorting.

Nov 5, 2022 · How do you sort a list of lists by the second element using Python? To sort a list of lists by the second element in each list use the key parameter to either the .sort() list function (if modifying the original list) or the sorted() function (if returning a new list).

Feb 20, 2025 · Learn how to sort a list of tuples by the second element in Python. Explore different methods using lambda functions and the sorted() method with examples.

Mar 7, 2025 · In this example, we use the sorted() function to sort the sales_data list based on the product name (the second element of each tuple). The key parameter is set to lambda x: x[1] indicate that we want to sort based on the second element. The sorted() function returns a new list sorted_data with the tuples sorted alphabetically by product name.

Apr 9, 2024 · Use the key argument of the sorted() function to sort a list of tuples by the second element. The function will return a new list, sorted by the second tuple element. list_of_tuples, . key=lambda t: t[1] ) print(sorted_list) # 👉️ [(1, 20), (1, 30), (1, 50)]
