python - what is better approach to do? -



python - what is better approach to do? -

i have piece of cake returning none in case exception caught.

def getobject(ver): av = none try: av = gettestobject(ver) except exceptions.objectnotfound, err: _log.info("%r not found", obj.fromtestobject(ver)) homecoming av

or improve ?

def getobject(ver): try: av = gettestobject(ver) except exceptions.objectnotfound, err: _log.info("%r not found", obj.fromtestobject(ver)) else: homecoming av

a shorter (more pythonic, imho) equivalent first code snippet follows:

def getobject(ver): try: homecoming gettestobject(ver) except exceptions.objectnotfound, err: _log.info("%r not found", obj.fromtestobject(ver))

this works because python functions implicitly homecoming none if command reaches end of function without encountering return (as case if exception caught).

java - Bypassing "final local variable defined in an enclosing type" - i'm writing programme , i'm getting "the final local variable asd cannot assigned, since it's defined in enclosing type". i provide illustration not code produces error aswell. have arraylist utilize later (if define within button can't utilize later on), outside of button, pressing button should give values arraylist. in illustration "create new arraylist" cause same problem. button btn = new button("asd"); final arraylist asd = new arraylist(); btn.setonaction(new eventhandler<actionevent>() { public void handle(final actionevent event) { asd = new arraylist(); //here's error.. } }); clear arraylist , add together values. java javafx
