Sets part -02 -19

Python sets second part
====================================
1. Union set
A = {1,2,3}
B = {3,4,5}
#Symbolic method
print(A | B)
Output: {1, 2, 3, 4, 5}
# union() method
A.union(B)
Output: {1, 2, 3, 4, 5}

2. Intersection Set
A = {1,2,3}
B = {3,4,5}
#Symbolic method
print(A & B)
output: {3}
#intersection() method
A.intersection(B)
Output: {3}

3. Set Difference
A = {1,2,3}
B = {3,4,5}
#Symbolic method
print(A - B)
output:{1, 2}
#intersection() method
A.difference(B)
Output: {1,2}
B.difference(A)
Output: {4,5}

4. Symmetric difference set
A = {1,2,3}
B = {3,4,5}
#Symbolic method
print(A ^ B)
output:{1, 2, 4, 5}
#symmetric_difference() method
A.symmetric_difference(B)
Output: {1, 2, 4, 5}
B.symmetric_difference(A)
Output: {1, 2, 4, 5}

5. Equal set
A= {1,2,3}
B = {2,1,3}
print(A == B)
output: True

6. Subset
A = {1,2,3,4}
B = {1,2,3}
print(A.issubset(B))
Output: False
print(B.issubset(A))
Output:True

7. Set Membership test
me = set("vubon")
#test
print('v' in me)
Output: True
print('n' not in me)
Output: False
print('z' in me)
Output: False # Because there is not z letter in vubon .

There are more methods in set. You can check out Python Docs. But I have discussed lot of things. Initially has been discussed all primary methods.
