Python yield from usage

Reading data from a generator using yield from

DefReader():    "" A generator that fakes a read from A file, socket, etc. "" " ForIInchRange(4): Yield ' <<%s ' %IDefReader_wrapper(G): # Manually iterate over data produced by reader ForVInchG: Yield Vwrap = Reader_wrapper ( reader ()) for I in Wrap: print  (i) # Result << 0<< 1<<< Span class= "PLN" > 2<< 3                

Instead of manually iterating over reader() , we can just yield from it.

def reader_wrapper(g): yield from g

That works, and we eliminated one line of code. And probably the intent is a little bit clearer (or not). But no life changing.
