python how to get element from set code example

Example 1: python sets

# 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 unordered

Example 2: get length of set python

# Create a set
seta = {5,10,3,15,2,20}
# Or
setb = set([5, 10, 3, 15, 2, 20])

# Find the length use len()
print(len(setb))
