PYTHON ADVANCED - 04: SETS

 IN THIS TUTORIAL, YOU WILL LEARN ABOUT SETS:

NOTE: TRY ALL METHODS WHICH ARE COMMENTED OUT(GREEN LINES)

#sets : unordered, mutable, no duplicates

# myset = {1,2,3,1,3}

# print(myset)

# mySet = set([1,2,3])

# print(mySet)

# myset = set("hello")

# print(myset)

# myset  = set()  #{} = class dict

# print(type(myset))

myset = set()

myset.add(1)

myset.add(12)

myset.add(13)

# if 1 in myset:

#     print("yes")

# else:

#     print("no")    

# for i in myset:

#     print(i)

#  myset.remove(13)

# myset.pop()

# print(myset)

# odds = {1,3,5,7,9}

# evens = {0,2,4,6,8}

# primes = {2,3,5,7}

# u = odds.union(evens)  #--> combines elements of two sets

# print(u)

# i = evens.intersection(primes)

# print(i)

# setA = {1,2,3,4,5,6,7,8,9}

# setB = {1,2,3,10,11,12}

# diff = setB.difference(setA)

# print(diff)

# diff = setA.symmetric_difference(setB)

# print(diff)

# setB.update(setA)

# print(setB)

# setA.intersection_update(setB)

# print(setA)

# setA.difference_update(setB)

# print(setA)

# setA.symmetric_difference_update(setB)

# print(setA)
