Python Sets Tutorial

A Set in Python is an unordered collection of unique elements. Sets are useful when you want to store non-duplicate items and perform mathematical operations like union, intersection, etc.

Python में Set एक unordered और unique elements का collection होता है। Set का उपयोग ऐसे data को store करने में किया जाता है जिसमें डुप्लीकेट न हों और mathematical operations जैसे union, intersection करना हो।

1. Creating a Set

my_set = {1, 2, 3, 4}
print(my_set)Copy

Output:

{1, 2, 3, 4}

2. Add Elements

my_set.add(5)
print(my_set)Copy

Output:

{1, 2, 3, 4, 5}

3. Remove Elements

my_set.remove(3)
print(my_set)Copy

Output:

{1, 2, 4, 5}

4. Loop Through a Set

for item in my_set:
    print(item)Copy

Output:

1
2
4
5

5. Union of Sets

a = {1, 2, 3}
b = {3, 4, 5}
print(a.union(b))Copy

Output:

{1, 2, 3, 4, 5}

6. Intersection of Sets

print(a.intersection(b))Copy

Output:

{3}

7. Set Length

print(len(my_set))Copy

Output:

4
