Ich habe versucht, "listwrite" googeln aber nicht helfen.

Ich bin sicher, das ist eine sehr einfache Sache, aber ich kann es nicht herausfinden.

def listwrite(output_file,thelist): 
    for item in thelist: 
     item.encode('utf-8') 
     output_file.write("%s\n\n" % item) 

Im Code wird listwrite als eine Funktion definiert. Für jede item in thelist schreibt es die item, gefolgt von zwei Newline-Zeichen. Um die zusätzliche Leitung zu entfernen, entfernen Sie einfach einen der \n s.

def listwrite(output_file,thelist): 
    for item in thelist: 
     item.encode('utf-8') 
     output_file.write("%s\n" % item)
