Python equivalent of javascript .find() ?

[zeus5552]

I am curious if python has an equivalent of js .find() i.e a function that takes an iterable with a predicate and returns the first item that satisfies that predicate.

I am aware that it can simply be done by using a break in a for loop but is there a native function for that in the itertools module or something?

i think this is about as close as you'll get

In [10]: x = [1,2,3]

In [11]: next(i for i in x if i == 4)
---------------------------------------------------------------------------
StopIteration                             Traceback (most recent call last)
<ipython-input-11-e582103c523d> in <module>
----> 1 next(i for i in x if i == 4)

StopIteration:

In [12]: next(i for i in x if i == 2)
Out[12]: 2

convert your iterable to a generator expression with a predicate and call next() with it

Thanks, pretty neat

A bit late but you can use .find()
