![]() ![]() However, to arrange the output in descending order: Alist. However, you can modify the order from ascending to. Related: What Is a Set in Python and How to Create One The sort() method is a built-in Python method that, by default, sorts the list in ascending order. On top of that, each nest in the list must belong to the same data type. Note that this doesn't work with a Python set since you can't index it. ![]() In the output above, the third item in each tuple increases from zero to twenty consecutively. You can sort a nested list of tuples by the index of each nested element in that list.įor example, the code below uses the third item in each tuple to sort the list in ascending order: Alist = You can also use a lambda function with sort() for cleaner code: myArray.sort(key = lambda getTime: getTime) You can also sort the tasks in reverse order by setting reverse to true: myArray.sort(key = sortByTime, reverse = True) To sort by string in the example array, you only need to change Time in the square bracket to Task: myArray = [ To sort the list, we can just use the function sort() for sorting in ascending as it is the default if not specified else to we can specify the reverse. In addition to sorting the array above by time, you can also arrange it alphabetically using the tasks, which are strings. The different implementations of sorting techniques in Python are: Bubble Sort Selection Sort Insertion Sort Bubble Sort. Related: How Arrays and Lists Work in Python ![]() Since the values of time are integers, the above block of code rearranges the array based on the task time. Let's sort the tasks in the dictionary below by their time: myArray = [ You can use the sort() method to sort a list of dictionaries as well. How to Sort a List of Dictionaries in Python MyList.sort(reverse = True, key = sortLength) To do so, create a function and pass it into the sort() method using the optional key argument: myList = You can also arrange the items in a list by the length of each string. You can use the reverse argument to view the list in descending order: myList = List.sort(key = function, reverse = True/ False)īy default, the sort() method arranges the items of a list in ascending order: myList = ![]()
