私はoutput.txtファイルを持っています。ユーザーがチャンネル番号を入力すると、その全体のイベントを削除したいと思います。

たとえば、ユーザがChannelNr=102と入力した場合、'BOOK:688045263' 番を取得できたら、channelNrに関連するイベントを削除できます。

次の関数を使用してファイル内にchannelNrを取得できます。関連ChannelNr上：

だから、私の質問はどのように本の数（688045263のitemId =」BOOK）を得ることができるのですか？

Answer 1

グーグルの最初の悔恨はhttps://www.tutorialspoint.com/python/string_find.htmです。それは良いリソースを持っています。

string.find（）は、たとえば、インデックスを返します。

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

print str1.find(str2) 
15 

これは正規表現ではありません。それは正規表現ですか？

JSONにエクスポートできますか？それははるかに、はるかにクリーンなソリューションとなり、頭痛のトンを節約します。今、あなた

{ 
"channelNr": 602 
} 

を与えるあなたが戻ってデータを取得することができます

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

としてこのテキストはあなたが

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

を試みることができる

あなた出力

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

、それは

return(channelNr == 602) 
True 

Answer 2

私はすでにchannelNrを取得しています検索します。私の質問は、どのように私はBOOK idsを得ることができる、私はイベントを削除することができますでした。

イベントはoutput.txtファイルにエクスポートされます。

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!' 

book変数は、delete_events（）関数でハードコードされています。私はトラフの本ID（9桁）を動的に渡す方法を見つけようとしています。
