子，不能連接「STR」和...對象

Question

我有這樣的代碼：

if len(sys.argv)>1: 
    host = sys.argv[1] 
    number = sys.argv[2] if len(sys.argv)>2 else "1" 
    size = sys.argv[3] if len(sys.argv)>3 else "56" 
    timeout = sys.argv[4] if len(sys.argv)>4 else "1" 

     proc = subprocess.Popen(["ping \"" + host + "\" -c \"" + number + "\" -s \"" + size + "\" -W \"" + timeout + "\" 2>/dev/null | grep packets | sed 's/[^0-9,%]*//g'"], stdout=subprocess.PIPE, shell=True) 
     (out, err) = proc.communicate() 

    print "address=\"" + host + "\" data=" + out 

我需要拆分出來上市。我如何實現這一目標？
一切我嘗試的原因錯誤：cannot concatenate 'str' and ... objects

就像當我嘗試：

... 
    res=list(out) 
     print "address=\"" + host + "\" data=" + res 

我得到錯誤：

TypeError: cannot concatenate 'str' and 'list' objects

團結字符串和列表，你首先必須做一個串出來的列表：

res=list(out) 
    print "address=\"" + str(host) + "\" data=" + str(res)
