Python has two basic function for sorting lists:sortandsorted. Thesortsorts the list in place, while thesortedreturns a new sorted list from the items in iterable. Both functions have the same options:keyandreverse. Thekeytakes a function which will be used on each value in the list being ...
You can sort a list of lists in Python using thesorted()function. By default,sorted()sorts the elements of a list in ascending order. To sort a list of lists based on a specific element in each sublist, you can pass a custom sorting function to thekeyargument. In this article, I wil...
Here, the sublists are sorted based on their second element (index1) in descending order. Sort a List of Lists in Python Using thelambdaExpression Along With thesorted()Function In addition to the combination ofitemgetter()from theoperatormodule andsorted(), Python offers an alternative method ...

is the first element retrieved (“first-in, first-out”); however, lists are not efficient for this purpose. While appends and pops from the end of list are fast, doing inserts or pops from the beginning of a list is slow (because all of the other elements have to be shifted by one...
fruits=['apple','banana','orange','grape']print(fruits[0])# Access the first elementprint(fruits[2])# Access the third element 1. 2. 3. Output: apple orange 1. 2. Slicing a list Slicing allows you to extract a subset of elements from a list. It uses the colon:operator to specif...
To sort a list of lists using the itemgetter() method, we will follow the following approach. Suppose that we have to rearrange the inner lists based on the element at the index n. First, we will create an itemgetter object get_n using the itemgetter() method. After that, we will pa...
sort the list of fruits according to the length of the values of letters in words in the list given. In this, we have a key function as len() function; as we can see in the above program, we have specified key as func, which is the function name that is first defined and created...
Extend the list by appending all the items in the given list; equivalent toa[len(a):]=L. list.insert(i,x)#将元素插入到指定的位置(位置为索引为 i 的元素的前面一个) Insert an item at a given position. The first argument is the index of the element before which to insert, soa.insert...
When sorting a list of tuples, Python sorts them by the first elements in the tuples, then the second elements, and so on. To effectivelysort nested tuples, you can provide a custom sorting key using thekeyargumentin thesorted()function. ...
