![]() ![]() Printing the planets list shows it is updated, and sorted in ascending order of the second element of the tuple.The output displays the result of the lambda expression passed in for the key parameter of list.sort(): The easiest way to sort is with the sorted(list) function, which takes a list and returns a new list with those elements in sorted order. print("In-Place Sort: ",planets.sort(key = lambda x : x)) ![]() The in-place sort returns a value of none but the original list is sorted. The lambda expression sorts the list by the second element of the tuple value and updates the original. In this section, we will take various examples of different data typed lists and will sort them using this method. It is a built-in function that sorts a given list ( either in ascending or descending order). We had already discussed the syntax of the python sort() method. The arguement x is the iterable element ( tuple) to be sorted by the second element, the number. Examples of Python sort list using sort() method. We can sort kinds of data by just calling sort function. The list.sort() method key parameter is set to lambda. Like the common high-level languages Python encapsulates sophisticated sorting functions. The newList is listed in reverse numerical descending order. The sorted() function returns a new list object, assigned to the newList variable. This output shows the lambda function change the default sorted() function parameter values. newList = sorted(planets, key = lambda x : x,reverse=True) The list is sorted on the second element of the tuple which is the number, and the reverse parameter is set to true. The sorted() function takes the planets list as data, the lambda sets the function key parameter. Learn how to specify a sort key to sort a dictionary by value, key, or nested attribute. The following examples will be used to illustrate how lambda functions can enhance or extend the functionality of the list.sort() method and sorted() function using the key parameter. Understand how dictionaries are cast to lists during sorting. We’ll use the planet list of tuples in the following example: //List of Tuples Declaration ![]()
