python - 函數不返回完整輸出

-1

我試圖從顯示庫存中獲取開關的模型no，然後將整數設置爲交換機所具有的端口數量。 ive試圖讓結果進入一行，然後用正則表達式搜索（正則表達式的作品，我測試它在http://regexr.com/）python - 函數不返回完整輸出

它看起來不像我的函數正在返回完整的庫存，它被截斷。它應該返回下面的

Switch#sh inventory 
NAME: "1", DESCR: "WS-C2960X-24PS-L" 
PID: WS-C2960X-24PS-L , VID: V01 , SN: XXXXX

這是輸出即時得到

Switch# 
Switc 
Object is: terminal length 0 
Switch#sh inventory 
NAME: 
Inventory is: 
Port Count is: 0

，這是腳本

    while not reponse in receive_buffer: 
     # Flush the receive buffer 
     receive_buffer += shell.recv(1024) 

    # Print the receive buffer, if necessary

寫'不是在b'中是不好的形式。相反，你應該使用'a not in b'。 –

，似乎已經修復了輸出，objInv字符串現在已填充，但strInv是關於此的任何想法 – AlexW

？掙扎很多... – AlexW

更換新線路和休息，並用找到的，而不是正則表達式和其fixex！

objInv = Send_Command_and_Get_Response("sh inventory\n", "#", False) 
print "Object is: " + objInv 

strInv = str(objInv) 
strInv = strInv.replace('\n','').replace('\r','') 

intPort = 0 
if (strInv.find('WS-C') >-1 and strInv.find('-24') >-1): 
    intPort = 24 
if (strInv.find('WS-C') >-1 and strInv.find('-48') >-1): 
    intPort = 48
