Python 2.7 Itertools Starmap

Have a function, func which takes two string arguments, The first one works, but according to the itertools documentation, shouldn't the second one work also? The function currently prints a random string, in return, but in the second nothing gets printed

func(*("dog", "cat")) //works

itertools.starmap(func, [("dog", "cat")]) //fails without error message, nothing gets printed to screen

Perhaps it is too late (or early) at night, am I missing a glaring mistake here?

Solution

  • itertools.starmap returns an iterator; to actually get it to execute you need to iterate through it e.g. using list:

    list(itertools.starmap(func, [("fall", "2007")]))
