Sometimes, we want to get the first item from an iterable that matches a condition with Python.
In this article, we’ll look at how to get the first item from an iterable that matches a condition with Python.
How to get the first item from an iterable that matches a condition with Python?
To get the first item from an iterable that matches a condition with Python, we can use the next function.
For instance, we write:
a = [1, 2, 3, 4, 5, 6]
first = next(x for x in a if x > 3)
print(first)
We define the list a that has some integers in it.
And we get the all the integers that’s bigger than 3 with x for x in a if x > 3 and return the list.
Finally, we get the first one on the returned list with next and assign it to first.
Therefore, first is 4.
Conclusion
To get the first item from an iterable that matches a condition with Python, we can use the next function.
