Sets in Python: .issuperset(), .union(), .discard() Part 2 - Series A
This is the second of two videos where I go over the basics of how to work with "Sets" in Python. I am not an expert when it comes to Python, but I know that teaching a subject helps solidify the information learned about.
This is Series A
Series A = 1
Series B = 2
Each series is intended to be better than the last because of all the practice I'll get from creating them.

Sets
An unordered pair of UNIQUE objects
set_1 = {'a', 'b', 'c'}
set_2 = {'c', 'd', 'e', 'f', 'g', 'h'}
print(set_1.union(set_2))
https://www.w3schools.com/python/pyth...
-------------------------------
.difference()
.discard()
.difference_update()
.intersection()
.isdisjoint()
.issubset()
.issuperset()
.union()
---------------------------------------------------------------------------------------------------------------
set_1 = {'a', 'b', 'c', 'v', 'w', 'p'. 'e', 't'}
set_2 = {'c', 'd', 'e', 'f', 'g', 'h', 'n', 's'}
1. How can you identify the different objects between set_1 and set_2?
2. What happens when None is returned as an output?
3. How can you get rid of an object in a set?
Remove 'a' from set_1 and 's' from set_2
How can you remove 'c'
4. If you remove an object from a Set is the removal permanent? When is it not permanent?
5. What is the difference between .discard() and .difference_update()?
---------------------------------------------------------------------------------------------------------------
6. How can you identify the overlap between the two sets below?
one_set = {1,2,3,4,8,9,7,4,2,1}
two_set = {1,2,5,7,3,8,9,3}
# 7. How can you idetnify if a Set has values that are shared with another Set? How can you return a boolean value?
---------------------------------------------------------------------------------------------------------------
8. Is one_set a subset of two_set?
Which items would need to be removed/added to make one_set a subset of two_set?
9. Is one_set a superset of two_set?
Which items would need to be removed/added to make one_set a superset of two_set?
10. What is the difference between a subset and a superset?
---------------------------------------------------------------------------------------------------------------
11. What could you do to join the two sets below together?
three_set = {'a', 'b', 'c'}
four_set = {'d', 'e', 'f', 'g', 'h', 'i'}
#
# 12. What method or function could you use to organize the joined sets?
This topic was not covered in the video but it is possible to organize the output to look like -
{'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i'}
#
#
# HINT - the method and function both begin with the letter s
