.set() in python code example

Example 1: python set

# A set contains unique elements of which the order is not important
s = set()
s.add(1)
s.add(2)
s.remove(1)
print(s)
# Can also be created from a list (or some other data structures)
num_list = [1,2,3]
set_from_list = set(num_list)

Example 2: set() python

#help set the array in python in order

Example 3: sets in python

set_of_base10_numbers = {1, 2, 3, 4, 5, 6, 7, 8, 9, 0}
set_of_base2_numbers = {1, 0}

intersection = set_of_base10_numbers.intersection(set_of_base2_numbers)
union = set_of_base10_numbers.union(set_of_base2_numbers)

'''
intersection: {0, 1}:
	if the number is contained in both sets it becomes part of the intersection
union: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}:
	if the number exists in at lease one of the sets it becomes part of the union
