Python Tutorials - Sorted Function | How to Sort List Tuple and Dictionaries

In this Python programming video tutorial we will learn how to sort list tuple dictionaries using sorted function in detail.
Sorted is builtin function can be used to sort iterables, which will return a new list with sorted elements.
Syntax of sorted function is:
sorted(iterables, key = None , reverse = false)
Here in this tutorial we will discuss about key function and reverse in detail with example.

which data structures can the key be used in? we can do the same in lists too right? Thanks for tips

[@redmi9power879]

Thank you ma'am I was frustrated from the key function but clear all my douts related to key function

[@ikamesh1390]

Hi Can we use sorted() for nested dictionaries? for ex cars = {"bmw":{"model":"rv10","Gear":"Auto","Year":2016},"Benz":{"model":"rv20","year":2019},'Audi':{"model":"rf30", "year":2019}} We can only use sorted() on keys. What if we want to do it for values and items?

Mam for dict can't we use def method instead of lambda

[@steephansteephan1360]

Thank you very much mam, very useful

[@somayehmadadpour8833]

Hello dear. Why defining function to manipulate items does not work for dictionary? Because we used it for tuple and list but not dictionary and instead you used lambda.

Python program to get a list, sorted in increasing order by the last element in each tuple from a given list of non-empty tuples.. can anyone explain me in detail?

Really helpful video.....❤️

[@AmulsAcademy]

Glad to hear that :)

[@77Sherms]

In reference to the key function, how does it know to skip the item at the next index so it sorts based on the letter? I.e. 'a' is at index [1] (which you put in the return statement) and then it sorts based on every item at every second index. So its sorting based on items at indexes [1] [3] [5 ][7] or does the indexing for each nested tuple start again? So the index number for each letter in the nested tuple is [1]? Also, I note that when you call the function in the sorted method you do not use parentheses at the end of the function I.e. normally when you call a function you put Secondvlaue(). Why is the parentheses at the end of the function not required when using it in the sorted function? Thanks. Good video btw.

[@77Sherms]

Additional: I played around with indexing nested tuples and discovered that if you want to access a single item in a nested tuple you have to specify the index of the nested tuple and the index of the item in the nested tuple. I.e. [0][0] will retrurn item 1 from (1, 'a').

[@AmulsAcademy]

Hey if i take nested list like this: list1 = [[1,2],[3,4]] if i want to access 1 then i need to take list1[0][0] because in list1 [1,2] list index is 0 [3,4] list index is 1. in the inner lists, list [1,2] index of 1 is 0 and 2 is 1. and also in list [3,4] index of 3 is 0 and 4 is 1. functions are called without parenthesis because parenthesis are added to key function inside the code written for sorted function. :)

[@77Sherms]

@@AmulsAcademy thanks. I still don't understand how the secondVlaue() function knows to call the second item in the first, and subsequent, nested tuples with the use of only one index. To call second item in the nested tuple, shouldn't it be [0] [1]?

[@PoojaYadav-fu6oy]

Ma'am you are awesome thankyou ma'am 😘💖

[@AmulsAcademy]

Most welcome 😊

[@eshwarvecham3647]

Mam, the function secondvalue is accepting one argument but when we are calling the function i.e used in key we are not passing any argument. Can u clarify my doubt.

[@AmulsAcademy]

It will take iterable(the first value in the sorted(), list,dictionary,tuple) as argument to the function.

[@eshwarvecham3647]

Ok mam thnks for ur reply. The function will be applied on each element of iterable? The secondvalue function is called as many times as the elements in iterable?

[@blatogh1277]

it is so clear OMG

[@AmulsAcademy]

Thank you :)

[@kushaldas8496]

Mam at 5.30 I can't understand here how lambda function works? Can you please explain me please mam 🙏

[@AmulsAcademy]

it will return the first element of the dictionary item.

[@Viralvlogvideos]

AWESOME TUTORIAL BRUH, whats is ur age ??

[@homataha5626]

what if we wanted to sort the tuple by the second element?

[@samrasoli]

items2 = [ (10, "product1"), (23, "product3"), (4, "product2") ] print(items2) items2.sort(key=lambda x:x[1]) print(items2)

You can use sorting algorithms. Bubble sort Merge sort ..... :)
