SetA 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 ExampleRYB_color = {"Red","Yellow","Blue"}
print(RYB_color)
>>> {'Red','Yellow','Blue'}
|
The set() ConstructorRYB_color = set(("Red","Yellow","Blue"))
|
Access ItemsExample 1
for x in RYB_color:
print(x)
>>> Red
>>> Yellow
>>> Blue
Example 2
print("Yellow" in RYB_color)
>>> True |
Change ItemsSince a set is not orderer neither indexed, then we cannot acces to any item to change its value. |
Add ItemsRYB_color.add("White")
print(RYB_color)
>>> "Red","White","Yellow","Blue"
|
Get the Length of a Setprint(len(RYB_color))
>>> 3
|
| | Remove ItemRYB_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. | RYB_color.clear()
| clear() returns an empty set.
|
Join Two SetsSecond_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.
