Sometimes, we want to extract the n-th elements from a list of tuples with Python.
In this article, we’ll look at how to extract the n-th elements from a list of tuples with Python.
How to extract the n-th elements from a list of tuples with Python?
To extract the n-th elements from a list of tuples with Python, we can use list comprehension.
For instance, we write:
elements = [(1, 1, 1), (2, 3, 7), (3, 5, 10)]
n = 1
e = [x[n] for x in elements]
print(e)
We get the n-th element from each tuple and put them into a list with [x[n] for x in elements].
x is the tuple being retrieved.
Therefore, e is [1, 3, 5].
Conclusion
To extract the n-th elements from a list of tuples with Python, we can use list comprehension.
