Python Set Intersection
The intersection of sets means finding common elements between two or more sets.
In Python, you can use the intersection() method or the & operator to find common items.
Set का intersection का मतलब होता है दो या अधिक sets के बीच common elements निकालना।
Python में intersection() method या & operator का इस्तेमाल किया जाता है।
Methods to Find Intersection
- set1.intersection(set2): Returns a new set with common items.
- set1 & set2: Shorthand operator for intersection.
- set1.intersection_update(set2): Updates the set in place with common items.
- set1.intersection(set2): एक नया set return करता है जिसमें common items होते हैं।
- set1 & set2: intersection के लिए shorthand operator।
- set1.intersection_update(set2): set को inplace update करता है सिर्फ common items से।
Example 1: Basic Intersection Using intersection()
a = {1, 2, 3}
b = {2, 3, 4}
print(a.intersection(b))Find common elements between two sets using intersection().
intersection() से दो sets के common elements निकालें।

Example 2: Using '&' Operator
a = {10, 20, 30}
b = {20, 30, 40}
print(a & b)Use & operator to find intersection.
& operator से intersection निकालें।

Example 3: Intersection of Three Sets
a = {1, 2, 3}
b = {2, 3, 4}
c = {3, 4, 5}
print(a.intersection(b, c))Find common elements among three sets.
तीन sets के बीच common element निकालें।
Output:आउटपुट:
Example 4: Using intersection_update()
a = {1, 2, 3, 4}
b = {2, 4, 6}
a.intersection_update(b)
print(a)Update set a with only the common elements using intersection_update().
intersection_update() से set a को सिर्फ common elements से update करें।
Output:आउटपुट:
Example 5: No Common Elements
a = {1, 2}
b = {3, 4}
print(a.intersection(b))If there are no common elements, result is an empty set.
अगर कोई common element नहीं है, तो empty set मिलेगा।

Example 6: Intersection with Strings
a = set('hello')
b = set('world')
print(a & b)Find common characters between two strings by converting them to sets.
दो strings को set में बदलकर उनके common characters निकालें।
Output:आउटपुट:
Example 7: Intersection with Range
a = set(range(1, 6))
b = set(range(4, 9))
print(a.intersection(b))Find common numbers between two ranges.
दो ranges के बीच common numbers निकालें।
Output:आउटपुट:
Example 8: Intersection with Duplicate Values
a = {1, 1, 2, 2, 3}
b = {2, 2, 3, 3}
print(a & b)Sets ignore duplicates, so intersection works on unique items only.
Sets duplicates ignore करते हैं, इसलिए intersection सिर्फ unique items पर काम करता है।
Output:आउटपुट:
Example 9: Using Loop to Find Intersection
a = {1, 2, 3}
b = {2, 3, 4}
common = {x for x in a if x in b}
print(common)Find intersection manually using loop comprehension.
loop comprehension से manually intersection निकालें।

Example 10: Intersection with Different Data Types
a = {1, 'a', (2, 3)}
b = {'a', (2, 3), 5}
print(a & b)Intersection can work with mixed data types, as long as they are hashable.
Intersection mixed data types पर भी काम करता है, बशर्ते वे hashable हों।
