46.1.1. Methods and Functions for set
(c) s1 = {1, 2}
s1.add(5)
s2 = s1.copy() will result in s1 = {1, 2, 5} and s2 = {1, 2, 5}
(e) You can have frozen sets as members of a set.
46.1.2. Write a Program to determine if a Set is a Subset of another Set
data1 = input("data1: ")
list1 = data1.split(",")
set1 = set(list1)
#fill in the missiong code
data2 = input("data2: ")
list2 = data2.split(",")
set2 = set(list2)
data3 = input("data3: ")
list3 = data3.split(",")
set3 = set(list3)
print("set1 sorted:", sorted(set1))
print("set2 sorted:", sorted(set2))
print("set3 sorted:", sorted(set3))
print("is set1 subset of set2?", set1.issubset(set2))
print("is set2 subset of set1?", set2.issubset(set1))
print("is set1 subset of set3?", set1.issubset(set3))
print("is set3 subset of set1?", set3.issubset(set1))
print("is set2 subset of set3?", set2.issubset(set3))
print("is set3 subset of set2?", set3.issubset(set2))
46.1.3. Write a Program to determine if Sets are Disjoint?
data1 = input("data1: ")
list1 = data1.split(",")
set1 = set(list1)
#fill in the missing code
data2 = input("data2: ")
list2 = data2.split(",")
set2 = set(list2)
data3 = input("data3: ")
list3 = data3.split(",")
set3 = set(list3)
print("set1 sorted:", sorted(set1))
print("set2 sorted:", sorted(set2))
print("set3 sorted:", sorted(set3))
print("is set1, set2 disjoint?", set1.isdisjoint(set2))
print("is set1, set3 disjoint?", set1.isdisjoint(set3))
print("is set2, set3 disjoint?", set2.isdisjoint(set3))
46.1.4. Write a Program to illustrate basic operations on Sets
data1 = input("data1: ")
list1 = data1.split(",")
set1 = set(list1)
data2 = input("data2: ")
list2 = data2.split(",")
set2 = set(list2)
data3 = input("data3: ")
list3 = data3.split(",")
set3 = set(list3)
set_1_2 = set1.union(set2) # perform union of set1 and set2, print the set.
print(sorted(set_1_2))
set_1_2_3 = set_1_2.union(set3) # perform union of set_1_2 and set3 and print it.
print(sorted(set_1_2_3))
# take an element from the user.
e = input()
# discard the user-given element from set_1_2_3.
set_1_2_3.discard(e)
print(sorted(set_1_2_3))
intersection = set_1_2.intersection(set_1_2_3) # find the intersection of set_1_2 and set_1_2_3 and print it.
print(sorted(intersection))
# check whether intersection is subset of set_1_2_3 or not and print the result.
print(intersection.issubset(set_1_2_3))
diff1 = set_1_2 - set_1_2_3 # find the difference of set_1_2 and set_1_2_3 and print it.
print(sorted(diff1))
diff2 = set_1_2_3 - set_1_2 # find the difference of set_1_2_3 and set_1_2 and print it.
print(sorted(diff2))
# take an element from the user.
e2 = input()
# add the user-given element to the diff2 and print diff2.
diff2.add(e2)
print(sorted(diff2))
# remove the user-given element from the diff2 and print diff2.
diff2.discard(e2)
print(sorted(diff2))
