Is it possible to unpack a tuple without using var

问题:

I'm using the os.path.split() function on a path in my program to get the filename and pathname of a file then passing them into another method, but my current solution seems rather ugly:

path = os.path.split(somefile)
some_class(path[0], path[1])

Is it possible to unpack the path tuple in a cleaner way within the call to some_class? Something like:

some_class(os.path.split(somefile).unpack())

Or should I simply be going about this another way? Maybe a more pythonic way?

回答1:

Yes, Python has argument list unpacking. Try this:

some_class(*os.path.split(somefile))
