What is the difference between a list and a set in Python? - Data Types and Data Structures Python में list और set में क्या अंतर है?

my_set = {1, 2, 3, 2, 1}   # {1, 2, 3}

# Set operations
set1 = {1, 2, 3}
set2 = {2, 3, 4}
union = set1 | set2  # {1, 2, 3, 4}
intersection = set1 & set2  # {2, 3}
difference = set1 - set2  # {1}
