Is declaration of sets & dictionary same? Like both of them uses { }
a = { }
For both is correct right ?

Set are unordered, have no durplicates, and don’t support indexing as a result.
Exactly the same as mathematical sets with union, and intersection operations

[debjyotichattopadhyay]

a=set("python", "data") is an invalid declaration
but
a={"python", "data"} is valid declaration
why is this so?? even when both are for declaring sets

Search for Arena Python swimming goggles brought me here. Not what I expected to find 🤔

Thanks Mosh!

A tiny experiment you could add is something like

knaagdir = {1, 4, 8, 3, 6, 4}
print(type(knaagdir))
print((knaagdir)) #aware of redundant parentheses but too lazy to remove them

Keep up the good work!

numbers = (1, 1, 2, 3, 4)
first = set(numbers)
second = (1, 5)

print(first | second)

When I do it, the vertical line is not accepted, it remains the same collor as first and second. How come? I believe this code is the same as what you did.

Mosh please upload your courses to Udemy, they are more affordable for people from poor countries like mine.

this is not a beginner friendly course, he doesnt stop to explain what he's doing he just throws it all at you. Mosh sucks.
