Searching a 2-Dimensional Tuple/List in Python
python
Solution
It does the trick but I've got this notion that there's probably a one-liner for it ;)
The one-liner is probably not the pythonic way to do it :)
The method you have used looks fine.
Edit:
If you want to be cute:
return next( (i for i,(k,v) in enumerate(items) if k=='Spock'),None)
`next` takes a generator expression and returns the next value or the second argument (in this case `None`) once the generator has been exhausted.
Problem
I want to search a `tuple of tuples` for a particular string and return the index of the parent tuple. I seem to run into variations of this kind of search frequently. What is the most pythonic way to do this? I.E: ``` derp = (('Cat','Pet'),('Dog','Pet'),('Spock','Vulcan')) i = None for index, item in enumerate(derp): if item[0] == 'Spock': i = index break >>>print i 2 ``` I could generalize this into a small utility function that takes an iterable, an index (I've hard coded `0` in the example) and a search value. It does the trick but I've got this notion that there's probably a one-liner for it ;) I.E: ``` def pluck(iterable, key, value): for index, item in enumerate(iterable): if item[key] == value: return index return None ```
