About JackscriptPy

Jackscriptpy is a python math library of sets. It covers a few useful functions involving sets that are otherwise not available in the standard python library.

Documentation:

This README does not cover the entire libraries documentation Read documentation from the https://jackscript.macbase.co.za The github of the documentation website is https://github.com/danielromeo/jackscriptDocs

How to create a set:

sets are created how you would normally create your set in python; as said earlier This library consnist of a set of functions and doesnt make any new data structures. Therefore all set methods from the python standard library will work like usual

mySet = set()

How to create a coordinate(coord):

coordinates are created as so

mycoordinate = coord(1, 2) # this sets x to 1 and y to 2

Advanced...

# add a coordinate to a set, using the coordinate created above:
myset.add(mycoordinate);

# as expected, the standard library methods will work as usual
myset.clear()
print(myset)  # returns set()

Checking whether a set is a subset of another...

set1 = {2, 5, 6}
set2 = {2, 5, 6, 9}

Looking at the above code; its clear that set1 should be the subset of set2, we get our answer by calling the function isSubset()

answer = isSubset(set1, set2) # returns True 
print(answer) # prints True

Simmilarly we can test if a set is a superset of another

set1 = {2, 5, 6}
set2 = {2, 5, 6, 9}

answer = isSuperset(set2, set1) # returns True 
print(answer) # prints True

Create a cartesian product

#create a cartesian product by calling the createCartesian() function

Check if a product is a relation of another

The function is called: isRelation()

""" 
	first create a cartesian product from sets:
	there are obviously multiple ways of creating cartesianProducts; we'll use more complicated route to demonstrate the use:
"""
# Create a couple of normal sets
normalset1 = {2, 3, 4} # another way would be: normalset1 = Set([2,3,4])
normalset2 = {2, 3, 4}
normalset3 = {2, 3}

cartesian1 = createCartesian(normalset1, normalset2);
cartesian2 = createCartesian(normalset1, normalset3); 

As you can see above; we used normalset1 and normalset3 to create a cartesian2

So technically, cartesianProduct2 should be a relation of cartesian1. We test this theory in the function below, in continuation of the above code.

print(isRelation(cartesian2, cartesian1)); # returns true
