I don't think it's well-defined. (But this is impossible and useless calling.) CMIIW? This is generic: >>> def f(): ... __gen= None ... def g(): ... i= 0 ... while 1: ... i+= 1 ... yield __gen( i ) ... def set( gen ): ... nonlocal __gen ... __gen= gen ... return g, set ... >>> a, set= f() >>> b= a() >>> set( lambda x: print( x ) ) >>> next( b ) 1 >>> next( b ) 2 >>> next( b ) -- http://mail.python.org/mailman/listinfo/python-list
