Set

Collection Type	Ordered	Mutable	Duplicate Elements	Indexing	Example
Set	No	Yes	No	No	{"a", "b", 23}

A set is a collection that is unordered and unchangeable* (in reality you can still add and remove elements). It does not allows to duplicate members.

# To create (instantiate)
a = {"a", "b", 23}  # cannot have doubles!

# To retrieve an element
impossible!  # only with list(a)[i]

# To remove an element
a.remove(“beam_12”)

# To insert an element
a.append(“post_01”)

🦊 set are often use for unique values. For example, if you want to find all the unique words in a text. You can use a set to do this. First, you would split the text into words. Then, you would add each word to a set. Since sets can only contain unique values, at the end you would have a set containing all the unique words in the text. This feature can be very handy! 🦊
