Python Tutorial : Sets

Sets are unordered, unique elements. The objects in the set must be unique ,duplicates can not be used in sets.

set_objects = {"boat", "sock", "phone","lamp"}
print(set_objects)

Check if certain objects are in set. If object is in the list system will print true and if object is not will print false

set_objects = {"boat", "sock", "phone","lamp"}

print("boat" in set_objects)
print("pen" in set_objects)

Strings can be pass in Set. It will iterate through the characters of the string as an object boat becomes “b”,”o”,”a”,”t”

set_object = "boat"

print(set_object)

Add objects to Set with add() or update()

add() is used to add one object

update() is used to add more than one object

# add() one object 
set_objects.add("bike")
print(set_objects)

# update() more than one object
set_objects.update(["kite", "ball", "hat"])
print(set_objects)

To remove an item in a set, use remove() or discard()

set_objects.remove("ball")
print(set_objects)


set_objects.discard("kite")
print(set_objects)

Get number of objects in set, use len()

print(len(set_objects))

loop through set objects

# loop through set
for x in set_objects:
  print(x)
