ファイルに書き込むときに余分な改行を削除する

Question

この小さなスクリプトは、ファイルにキーワードを書きますが、各キーワードの間に余分な改行を追加します。どうすればそれを止めることができますか？私。代わりに私が

の私は "listwrite" をグーグルで試みたが、助けにはなりませんでした。

これは非常に簡単なことだと確信していますが、わかりません。コードで

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

、listwriteを関数として定義されます。 itemはthelistで、itemとそれに続く2つの改行文字を書き込みます。余分な行を削除するには、\nのいずれかを削除するだけです。

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