Set
A set is a collection which is unordred and unindexed in a way that we cannot be sure in which order the items will appear. |
Set Example
RYB_color = {"Red","Yellow","Blue"}
print(RYB_color)
>>> {'Red','Yellow','Blue'}
|
The set() Constructor
RYB_color = set(("Red","Yellow","Blue"))
|
Access Items
Example 1 for x in RYB_color:
print(x)
>>> Red
>>> Yellow
>>> Blue
Example 2 print("Yellow" in RYB_color)
>>> True
|
Change Items
Since a set is not orderer neither indexed, then we cannot acces to any item to change its value. |
Add Items
RYB_color.add("White")
print(RYB_color)
>>> "Red","White","Yellow","Blue"
|
Get the Length of a Set
print(len(RYB_color))
>>> 3
|
|
|
Remove Item
RYB_color.remove("Yellow")
print(RYB_color)
>>> {'Red','Blue'}
|
If the item doesn't exist then remove()
will raise an error. |
RYB_color.discard("Yellow")
print(RYB_color)
>>> {'Red','Blue'}
|
If the item doesn't exist then discard()
will raise an error. |
c = thisset.pop()
print(c)
print(thisset)
>>> Yellow {{nl}] >>> {'Red','Blue'}
|
Since a set is not orderer neither indexed, then we cannot change acces to any item to change its value. |
|
clear()
returns an empty set. |
Join Two Sets
Second_color = {"Green","Orange","Purple"}
Color = RYB_color.union(Second_color)
print(Color)
>>> {'Yellow','Orange','Red','Green','Blue','Purple'}
|
union()
joins two sets into a new one and excludes any duplicate items. |
RYB_color.update(Second_color)
print(RYB_color)
>>> {'Yellow','Orange','Red','Green','Blue','Purple'}
|
update()
inserts the items in Second_color
into RYB_color
and excludes any duplicate items. |
