我有一個output.txt文件。當用戶輸入頻道號碼時，我想刪除整個事件。

例如，如果用戶輸入ChannelNr=102，那麼如果我可以取'BOOK:688045263' 號碼，我將能夠刪除與channelNr相關的事件。

我可以得到channelNr，如果它在具有以下功能的文件中。

所以，我的問題是如何能得到書號（的itemId =「書：688045263）對相關ChannelNr？

Answer 1

google中的第一個reult是https://www.tutorialspoint.com/python/string_find.htm，它有一些很好的資源。

string.find（）例如會給你索引。

str1 = "this is string example....wow!!!"; 
str2 = "exam"; 

print str1.find(str2) 
15 

但這不是正則表達式。是否需要正則表達式？

你可以將它導出爲JSON嗎？這將是一個更加清潔的解決方案，可以爲您節省大量頭痛。

你輸出這個文本作爲

channel = ("channelNr= '%d'") % (user_channel_number)

你可以嘗試

>>> import json 
>>> print json.dumps({'channelNr': user_channel_number}, separators=(',', ': ')) 

，這將給你

{ 
"channelNr": 602 
} 

現在你可以取回數據

jsonData = { "channelNr": 602  } 
dictionary = json.loads(jsonData)[0] 
channelNr = dictionary['channelNr'] 

，並搜索其

return(channelNr == 602) 
True 

Answer 2

我已經得到channelNr。我的問題是，我如何獲得BOOK ID，因此我可以刪除這些事件。

事件導出在output.txt文件中。

def check_channel_number(self): 

    print "***************Channel Checker *********************" 

    user_channel_number = int(re.sub('\D', '', raw_input("Enter a channel number, (3digit): "))[:3]); 

    self.user_channel_number = user_channel_number 

    channel = ("channelNr= '%d'") % (user_channel_number) 


    # book = ("BOOK: '%d") %() 

    datafile = file('output.txt') 

    found = False 

    for line in datafile: 

     if channel in line: 
      found = True 
      return user_channel_number 

     print 'The channel number you entered is not on the planner' 
     break   



def delete_events(self): 


    self.ucn = self.user_channel_number 

    are_you_sure = raw_input('Channel number is correct. Are you sure to delete channel number? (y/n): ') 

    if are_you_sure == 'y' and self.ucn >0 : 

     print 'The selected program will be deleted' 

     action = 'DeleteEvent' 
     menu_action = 'all' 
     book = 'BOOK:688045265' 
     arg_list = [('C:\\Users\\yke01\\Documents\\StormTest\\Scripts\\Completed' 
         '\\Utils\\UPNP_Client_Cmd_Line.py')] 
     arg_list.append(' --action=') 
     arg_list.append(action) 
     arg_list.append(' --ip=') 
     arg_list.append('10.10.8.89') 
     arg_list.append(' --objectId=') 
     arg_list.append(book) 

     subprocess.call(["python", arg_list]) 

     print 'The program deleted successfully' 
    else: 
     print 'The program is NOT deleted!' 

正如你所看到的書本變量在delete_events（）函數中被硬編碼。我試圖找到一種方式來動態傳遞槽書ID（9位數字）。
