How to not supply all the default arguments when calling Python function?

Let's say I have this function code: ``` def dosomething(thing1, thing2='hello', thing3='world'): print(thing1) print(thing2) print(thing3) ``` When calling it, I would like to be able to specify what `thing3` is, but without having to say what `thing2` is. (The code below is how I thought it might work...) ``` dosomething("This says 'hello fail!'", , 'fail!') ``` and it would say: ``` This says 'hello fail!' hello fail! ``` So is there a way to do it like that, or would I have to specify `thing2` every time I wanted to say what `thing3` was?
