Sometimes, we want to test if lists share any items in Python.
In this article, we’ll look at how to test if lists share any items in Python.
How to test if lists share any items in Python?
To test if lists share any items in Python, we can use the & operator after converting the lists to sets.
For instance, we write
bool(set(a) & set(b))
to converts lists a and b to sets with set.
Then we use the & operator to get the intersection of the sets.
And then we call bool to check if the intersection is empty or not.
Conclusion
To test if lists share any items in Python, we can use the & operator after converting the lists to sets.
