# You can't create a set like this in Python
my_set = {} # ---- This is a Dictionary/Hashmap
# To create a empty set you have to use the built in method:
my_set = set() # Correct!
set_example = {1,3,2,5,3,6}
print(set_example)
# OUTPUT
# {1,3,2,5,6} ---- Sets do not contain duplicates and are unorderedset in python
A_Set = {1, 2, "hi", "test"}
for i in A_Set: #Loops through the set. You only get the value not the index
print(i) #Prints the current valueset in python
#Definition: A collection of values (similiar spirit to python dictionary)
# implementing hash table as a data structure underneath the hood.Copyright © 2021 Codeinu
