Python Tutorials - List Sorting | sort method

[@fatinishraqprapya3139]

This is one of the best helpful video for the beginners who are learning Python.

[@sushilkumar-ef7gh]

I have to say that you have made coding more interesting then ever for me ....Thanks a lot

[@AmulsAcademy]

Welcome:)

[@babyfox205]

great explanation of the 'key' for sorting, your explanation was the best of all 5-6 that I've seen today and were unable to really understand why we can put any function into the key. Thank you!

[@denizyarar4781]

thank you i'm a year 11 student writing code for an NEA and this vid is a lifesaver

[@AmulsAcademy]

Thank you :)

[@fun-ih5sc]

9:18 . * When we call the userdefine function we are not passing any argument as but when you define the function it is taking one argument .How is it working. * key=SortBySec, here how the argument in function defination "Element" is pointing toward every index of a list Thanks & Regards Aditya

[@AmulsAcademy]

you should mention function name as key, no need to mention arguments. when you define key function it should contain only one parameter, if it contains more we will get error. when we use sort function it will take the first value of list and compare it with second element and based on the comparison it will sort the list. [when key is not mentioned]. when key is mentioned then instead of comparing first element with second, it will pass that first element to that function, next second element to that function later based on that function result it will sort the list. :)

[@qzorn4440]

this is sooo relaxing python information. I listen to your video on my coffee break to relax. S*) thanks

this information is so satisfying !!!Thank you so much Amuls Academy

[@AmulsAcademy]

Glad you liked it!

[@sangeethaagoudar2175]

This is one of the best video of knowing exactly how the nested list worked with sort .Thank you so much 😊

[@alimujtaba1208]

your teaching method is very best i satisfier

[@HarshRaj-bm9eg]

mam i am so so so thankful to u. you cannot even imagine what you are to me

[@AmulsAcademy]

Welcome:)

[@josephdzn9868]

good explanation. 2nd example can also be done by: list2.sort(key=lambda x: x[1])

[@ilzz9856]

Hi bro can u explain working of that expression?

[@josephdzn9868]

I am not an expert here (still learning) but you can think of lambda as a throw away function. No need to define a separate function but you can encapsulate expressions (and arguments) using lambda - if that makes sense. Amulya's channel clearly explains the Lamdba function, check that out.

[@mananbhatia9242]

how we can do to descending order using this function?

[@Suhail_202k]

Really one of the best videos on KZbin hatsoff ,great explanation mam thanks for your efforts,i hope you will do more videos ❤

[@nagapurisandeep2289]

Your explanation is good mam.

[@AmulsAcademy]

Thank you 😊

[@sairamnagarajan8289]

Simplistic explanation. Thanks for your effort.

[@AmulsAcademy]

My Pleasure :)

[@zhimwar1367]

Thank you so much for sharing this. U have solved one big question in head for long time.

[@AmulsAcademy]

Pleasure :) And that is ?

[@krishk4870]

hey i got doubt pls clear it... that in 7:55 how the fucn (sortbysec) is works its just return the parameter(element's) first indexing position,that how could sort the list regards with sec value of sublist of list2 ????????? pls xplain the key fuction def sortbysec() plsssssssss amul !!!!!!!!!!

[@AmulsAcademy]

key function serves as a key for the sort comparison, it won't sort the list. "key" function transforms each element before comparison, next based on that transformed value sort() will sort the list. :)

[@gani3676]

Hi Amul, Will be waiting for continuous video. Thanks

[@AmulsAcademy]

Thank you:)

[@ilzz9856]

In the video you done ascending order through first element and by second element . How can we make descending order in that list with second elements?

[@AmulsAcademy]

take reverse=True :)

[@steveaman5126]

nice in-depth knowledge

[@AmulsAcademy]

Thank you 😊

[@abdullakhan4632]

very good. i like your explanation. grate 👍👍👍

THANK YOU SO MUCH MA'AM YOU CLEARED MY DOUBT

[@AmulsAcademy]

It's my pleasure : )

[@itachi99887]

Do you have any video on how to sort tuple inside list . For eg [(as,1),(cs,2),(bs,6)] how to sort the key value in ascending order. If you have please give the link . Thank you

[@HarshRaj-bm9eg]

thank you very much for making such a very beautiful video based on python

[@AmulsAcademy]

Thank you:) Keep Learning

[@sanketh768]

Thanks for the video. But had 1 doubt which is still unclear def sortbysec(element):# accepts list as a parameter or argument return element[1] list=[(1,16),(1,2),(2,5)] list.sort(key=sortbysec)# my doubt is sort by sec is not taking any parameter as per the signature of this function. # we are not passing any argument to the sortbysec function i mean list2=sortbysec(list) # passing list as arguments Would greatly appreciate your help

[@AmulsAcademy]

No need to pass any parameter to key function :) You are calling list.sort(key) so whatever you will do with sort() will apply on list. :)

how come index of second element is one in nested list? it should be element[0][1], shouldn't it ?

mam one more thing i want to say to you is that can you tell me that from where can i get questions based on python for beginners as i am new to program. this is the first time i am learning any language and this is the python

google it, you can start with basic programs:)

How to get a list input.. Like this [1,2,3,4] as an input and print it like [4,3,2,1]

[@AmulsAcademy]

You want to reverse the list or want to sort?

[@swethamk5925]

I want to reverse the list

[@AmulsAcademy]

list1.sort(reverse=True)

[@mominumar3388]

How can we sort a list containing numbers as well as characters??

[@AmulsAcademy]

In python 3 it will give error But you can separately sort characters and numbers then you can append it to list. c = ['s', 'a',2 , 'j', 9, 'e', 11, 't', 'k', 12, 'q'] c = sorted([i for i in c if not str(i).isdigit()]) + sorted([i for i in c if str(i).isdigit()]) print(c) :)

[@1mol831]

Thanks, though I still want to learn how I could sort by frequency. Without using a while loop with a dictionary..

[@Sandeep0917]

can u solve this by using for loop
