Set is collection of unique elements, like in list if you repeat something i.e some number like 12 then it is repeated again, but in sets if you write 12 number 2 times then it will display only once, so this is 1st one. 2nd one is set is working on concept of hash, where list not working on concept of hash! 3rd one is in sets index number is not working, because sets can't maintain sequence, but list maintain sequence, eo index number is working in list! So these are some of difference between set and list! Thank you!

[@yatinkathuria5198]

Set is the collection of non repeated elements while list is the collection of any type of element and any number of times. Set is define by { } List is define by [ ]

[@niranjanns8704]

And one more thing, set never follows sequence whereas lists follows sequence

[@danieltochi5087]

1. Set is collection of objects which is shows in curly brackets{} wher list shows in square brackets[] 2. Set is collection of objects where repeation of objects is not allowed but in list repeation of objects is allowed. 3. In set indexing and slicing operation not applied bcz in set sequence is not defined but list performs indexing and slicing.

Bro i think set is mutable

[@aarathakkar2720]

Sets are mutable

[@mohankumar9511]

Sets are immutable we can able to add or remove a item from it but we can able to change any value because it doesn't maintain the sequence

A list is an ordered collection of elements that allows duplicate values, while a set is an unordered collection of unique elements. Lists are mutable, meaning you can change, add, or remove elements. Sets are also mutable, but they have built-in methods for set operations like union, intersection, and difference.

[@meetangad]

Set is a collection of unique elements whereas in list you can repeat elements. Also, when you call set variables, the elements thrown will not be in sequence and will be randomized unlike lists which will throw elements in sequence.

[@shankargope2475]

Fantastic👌, absolutely got crystal clear clarity regarding address of a value assigned to variable, a little bit clarity about garbage collection👍. These are most fundamental concepts and you have made it so easy to understand, love the way you teach❤ Difference between set and list --> List is ordered sequence data type containing similar or different type of collection of data within [ ], Set is a sequence data type but not ordered containing unique collection of datas (not reapted) within { }.

[@rachana7044]

Thank you..sir..it's really fun learning with you... Differences are set:unique elements, curly braces, not supports index,imutable List:collection of all types, bracket, mutable, support index value

Excellent video.... He is completely going in a proper way without skipping any topics.. Following the proper order..

[@arslankabeer3951]

Hello Navin, hope you're doing well. I have a question for you. How the Python is so memory efficient when you change the value of variable "a" it still remains in memory & Python creates a new variable which is named called "a" and it used some different memory address right? So everytime you change the value of "a" in program it consumes some extra memory in Python. Even on the other hand when we are using C++ this memory efficiency concept is true it will always point to the same memory address, doesn't matter how many times you change the value of that variable.

[@santiswaroopa3262]

sir, you are God of knowledge. Python is so easy because of your way of explaining.

[@shabbasaikia]

Set is mentioned when there're curly brackets. If you give any numbers, it'll show in an order which is not descending, nor ascending nor the order whatever you gave.

[@prathikbhat]

Set and List both are mutable in nature. The major differences are sets are represented by flower bracket or curly bracket while list in square bracket. Set is a collection of unique elements while list can have any elements including repeated values. Set won't have index value as it can't maintain sequence while lists can!

[@akshaykumarannigeri2458]

Hi naveen , if we want integer part in this programme a=2, b=5 and c=b/a and answer will be c=2.5 We can type int (c )and we will get 2, but what we have to do if we want that remaining 0.5

[@ishaandas6427]

Tbh he explains everything in such a way that the person who watches his video will be left with no clarifications, this is the best part of him, he explains everything so concise, which makes him a better programmer than mosh sorry mosh fans but this guy is truly a miracle ;)

[@yunpeiyang4904]

"Variables of the same value are given the same memory address" can sometimes work against you. Learned it the hard way from a code like this: a=[1,2,3] b=a for i in range(1,4): for num in a: b.append(num+i*10) The intent was to make a list of this pattern: [1, 2, 3, 11, 12, 13, 21, 22, 23, ...]. But since python uses the same memory address for a and b, appending list "b" will also change list "a". With the for loop trying go through a list that keeps expanding each iteration, the loop becomes infinite. To avoid this issue, make "a" a tuple (a=tuple(a)) after the line "b=a'. This will result in "a" and "b" having different addresses and less likely to be mixed up.

[@aparajita773]

1)set is a unique collection of values.hence it does not allow repeatation while lists don't have any such restrictions. 2)set does not follow any proper sequence of elements but lists do follow. 3)sets does not support indexing but lists do. 4)sets work on hash concept which focuses much on speed rather than sequence.hence they have faster excecution speed but lists are compartively slower.

Set is a collection of unique elements, it uses hashing techniques in which data is in random order, it is immutable, where as Lists is a mutable. List contain many methods where as set contains only 2methods:Index,count.

Set = doesn't mantain sequence, doesn't support dupplicate values List = collections of values. they can be the same or different. you can modify them

[@mihirvaghela2185]

we can also modify set right?

[@raviraimittal]

List is an ordered collection of elements in the data structure of Python which allows duplication and is defined by square brackets [ ]; SET is non ordered collection of elements which does not allow duplication of elements and is defined by curly brackets {}. since no duplication is allowed in sets it offers an advantage to look out for specific objects with more efficiency.

[@DHHcovers]

List is a collection of data, Data can be of different types, Lists can be mutable, Lists is denoted by [ ] square brackes where as in Sets, it do not follow any sequence and denoted by { } curly bracket.

[@AbhishekGupta]

Set vs Lists : 1. In lists when we input values the output will be same as input but when we use set it's not and if in set a number repeats itself more than once it will be printed once. 2.We cannot trace index of value in set whereas lists are capable of doing that. 3. lists are easy to manipulate rather than set as we know exactly where to add element but in set we can't add the value to required slot as in output it will vary with every change. 4.as set use hash concept which we can't find in lists but we can perform manual sorting,descending,deleting,adding in lists in more easier and efficient way.

[@56tejasbiranje93]

Set is collection of unique elements while in set the sequence is maintained and recurring elements are shown once only While 'Lists' are mutable and changed the data is put in square brackets. The values of list can be fetched by using index value. In case of set it can't be used

[@girijavarma5271]

Difference between SET and LIST are:- SET - set is a collection of unique elements. only immutable object can be stored LIST - mutable

[@jaikishankumarmore1457]

Set is an unordered collection of unique items, where as a list is an ordered collection of items. List can contain duplicates but a set doesn't allow duplicates. Both are immutable. As set is unordered, it doesn't support indexing but list does.

List is collection of data and there index is unique, we can fetch data by using index. While set is collection of unique data without any index.

[@coderkumar]

The fundamental difference between List and Set in Python is allowing duplicate elements. ... A list is an Ordered Collection while Set is an unordered Collection. List maintains insertion order of elements, means any element which is inserted before will go on the lower index than any element which is inserted after.

*Set* Set is a collection of unique elements & for creating set we use curly brackets {} ,and in set the numbers r not in sequence & here indexing is not supported n it will not support duplicated values *List* list is mutable...it means we can change the values in list. for creating lists we use square brackets []..

List is used to group different data types. List are mentioned in []. And indexing will be supported. List are mutable (we can change the value) Eg: x=['thankyou',10000] Set is the collection of unique elements. Set are mentioned in {}. And indexing in set are not supported. Sets are immutable (we cannot change the value) Eg: x={1,45,12,25,98}
