Case 1: Sort a List in Python in an Ascending Order. If your list contains string items, then the sort Python method will arrange the results in ascending order just like the numeric example. To customize the default sorting behavior, use the optional key argument by passing a function that returns a comparable value for each element in the list. By using the key parameter, we can define our own custom sort. Python List sort() The sort() method sorts the elements of a given list in a specific ascending or descending order. Task: You have a list of strings and you have to sort it. For this demo, I have created a list of strings that contains five color names. Let’s say that you created a simple list of names: names = ['Jon','Maria','Bill','Liam','Emma'] print (names) This is how the list would look like in Python: You can then sort the list of names in an ascending order by adding names.sort() to the code: An element of any type (string, number etc.) The list.sort() method sorts the list elements in place in an ascending manner. In Python, there are two ways, sort() and sorted(), to sort lists (list) in ascending or descending order. Python methods required for sorting. An example of sorting list of strings. By tweaking few lines of code, we can also sort the string in Python. Creating our own Program to sort the list of lists in Python Let us create a function which will sort the list according to the given columns number. Here is an example of the key argument in action that will sort our list by the length of its component strings: There are different ways to sort a Python list of strings in ascending or descending order. Python has its own implementation of sort() function and another is sorted() function where sort() will sort list whereas, sorted function will return new sorted list from an iterable. See online demo and code For example, we can sort an array by the length of the strings in the array. It follows the following steps: It follows the following steps: Each element of the list is temporarily replaced with a “decorated” version that includes the result of the key function applied to the element. def sort_lists(list1,c): for i in range(len(list1)-1): # if the next element is greater then the next element, swap it. Sort Python Keys. Sort By String Length. Insertion Sort for String in Python # This function takes unsorted array as an input # and returns sorted array. isalpha(): To check if the string contains any alphabet characters such as “A-Z” or “a-Z” append(): To appends an element to end of the list. Using sort() Using sorted() Sort List of Strings using list.sort() sort() is a method that can be applied only on lists. We are going to use these Python methods in our program for sort characters of the string. It happens all the time. There can be multiple scenarios possible while sorting a list of a sting in python, like:-Sorting in alphabetical/reverse order. Following are some of the ways we shall discuss to sort strings in Python. The difference between sort and sorted is that sort is a list method that modifies the list in place whereas sorted is a built-in function that creates a new list without touching the original one. These key function of Python’s while sorting implemented is known as the decorate-sort-undecorate design pattern. It is defined in list class. Here, for the first case, our custom function returns the name of each employee. Since the name is a string, Python by default sorts it using the … Python – Sort List of Strings. You have a python list and you want to sort the items it contains. Basically, you can either use sort or sorted to achieve what you want.. The list is displayed before and after using the sort method. We can sort our lists using our own methods of sorting. Sort list of strings with numbers; Based on the length of string character; Let’s see one by one every possible scenarios examples.
