Difference Between List, Tuple, Set and Dictionary in Python

This Tutorials explains the difference between List, Tuple, Set and Dictionary in Python

# DIFFERENCE BETWEEN
# LIST - square braces
# TUPLE - rounded braces
# SET - The set keyword
# DICTIONARY - curly braces: made up of key-value pairs

list1 = ["Computer", "Printer", "TV", "Camera", 89, 30.8]

tuple1 = ("Computer", "Printer", "TV", "Camera", 89, 30.8)

set1 = set(["Computer", "Printer", "TV", "Camera", 89, 30.8])
dict1 = {
1: "Monday",
2: "Tuesday",
3: "Wednesday"
}

I was looking for a concise video to explain all these 4 concepts and stumbled on this. I have used all concepts before and needed clarification but I think this content needs to be updated.

1. Sets can be created using {} without the need for the 'set' keyword. E.g., set1 = { 'a', 'b', 1 }
2. Dictionaries can be created using the same curly braces '{}' but will only be considered to be a dictionary if and only if it takes in keys and values, which is quite obvious.
3. The other way to make a list or a tuple or a set or a dictionary is by using their keywords. E.g., list(), tuple(), set(), dict().

I just thought to point this out. Hope it helps!

we can define set using {}, what you used is type caset.
for eg:
set1={"apple", "baanana", "orrange"}
print(set1)
print(type(set1))

Thank u I understood . Tomorrow is my computer science finals 😂

[MalPlayss]

This was really helpful and I understood everything. Thank you!

Starting my data science in a weeks time and was looking for the explanation of
1:list
2:Tuple
3:Set and dictionary and I found out that this is a perfect one - easy to understand

[AK-Star]

Good explanation,
Adding my further understanding where to use them;

List:

Used in JSON format

Useful for Array operations

Used in Databases

Tuple:

Used to insert records in the database through SQL query at a time.Ex: (1.’sravan’, 34).(2.’geek’, 35)

Used in parentheses checker

Set:

Finding unique elements

Join operations

Dictionary:

Used to create a data frame with lists

Used in JSON

Thank you - I wish you would explain WHY you would use dictionary vs set

[applymarket]

Perfect Explanation of these four! Thanks Bro!

[ramprakash]

Sir you mentioned that you need to use the keyword "set" to create a set. But it is not necessary, all you have to do is to enclose the data in curly braces. Eg: a={ 1, 2, 3}


If you need to create a dictionary then just add a key to the above set.
Eg: a={ "first" : 1, "second" : 2 }

[JJJJ-gluf]

Good intro to these Python topics. Thanks.

[RGMUTEX]

awesome thank you so much, its really helpful

[anirudhani]

And set can be directly mentioned with {} instead of set ([])

[Repentforthekindomogiah]

thankyou sir you are very much life saver you explain very well i have subscribed

[udayjkc]

Kindson bro, curly braces can be used to define set try This > set1={'a', 'b', 'c'}
print(type(set1))

[SageArbor]

Printing dictionary values by key ... for the above example code you could print out using

>print(dict1[2])
which would print "Tuesday"

For a more complicated example, if the third key instead of 3 was "thirdKey" then you could print it using :
>print(f'dict1[thirdKey] = {dict1["thirdKey"]}')

Oh u made my understand it like a penny task

Hey may I ask? What IDE are you using?

[makhzansabeel]

Well explained... It remove my doubts regarding these topics

[stonedead]

hi, thanks for the video.
whats' the IDE you're using on this video? it looks so cool and seems light, unlike the IDE I'm currently using. Takes time to load, and clumps most of my screen area.
