Certainly not.

I've never used py-serial, so I was hoping someone else would jump in 
with the best way to do this (or perhaps you can find it in the 
documentation). One way would be to use the iter() built-in to make it 
into an iterable, like this:

iterable = iter(s.readline, "")

Note that you do not call s.readline() here; you are only supplying the 
bound method itself as an argument. iter() will call it later. I'm 
assuming that s.readline returns an empty string when there is no more 
input. Please replace that with whatever end sentinel it actually uses. 
(None?)

Another way would be to use s.readlines(), which returns a list, which 
is iterable, but you would have to wait until the entire list were 
collected before beginning processing.
