Feld mit Python extrahieren

Question

Ich suche nach Hilfe, um ein bestimmtes Feld zu extrahieren. Hier

ist das Beispiel, ich bin nicht in der Lage zu spalten und schneiden basierend auf Feldnummer, weil Zahl aufgrund der Inhaltsänderung ändern kann

Beispiel 1

[["cn","Phone",1,"","LI(\"\")","0","19%","",""],["OS_DisplayName","Display Name",1,"","LI(\"\")","1,0","19%","",""],["OS_ProductPackage","Product Package",1,"","CO(\"\",\"REQ;1_BASIC!OS!TRV;2_Messaging!OS!OEM;3_Extended!OS!EAC;4_Enhanced!OS!APO;5_Analog Port!OS!CCA;6_Contact Center Agent\",\"\",\";\",\"\",\"\")","2,0","19%","",""],["sn","Last name",1,"","LI(\"\")","3,0","12%","",""],["givenName","First name",1,"","LI(\"\")","4,0","12%","",""],["OS_SiteCode","Site Code",1,"","LI(\"\")","5,0","19%","",""]],[["917845678923","Backup","OEM","917845678923","","CNdd_RD_91784567","","cn=917845678923,cn=Subscribers,cn=np_CNdd_RnD_WangJing,cn=IPC_APAC_1_01,cn=DN,cn=Resources,cn=Users,cn=OS"]], 

Output

sollte

Beispiel 2

[["cn","Phone",1,"","LI(\"\")","0","19%","",""],["OS_DisplayName","Display Name",1,"","LI(\"\")","1,0","19%","",""],["OS_ProductPackage","Product Package",1,"","CO(\"\",\"REQ;1_BASIC!OS!TRV;2_Messaging!OS!OEM;3_Extended!OS!EAC;4_Enhanced!OS!APO;5_Analog Port!OS!CCA;6_Contact Center Agent\",\"\",\";\",\"\",\"\")","2,0","19%","",""],["sn","Last name",1,"","LI(\"\")","3,0","12%","",""],["givenName","First name",1,"","LI(\"\")","4,0","12%","",""],["OS_SiteCode","Site Code",1,"","LI(\"\")","5,0","19%","",""]],[["868694755000","Yaeng Danning","EAC","Yaeng","Dainning","CNdd_DT_86869475","","cn=868694755000,cn=Subscribers,cn=np_CNdd_DN,cn=IPC_APAC_1_01,cn=DN,cn=Resources,cn=Users,cn=OS"]], 

Ausgabe sollte sein

cn=868694755000,cn=Subscribers,cn=np_CNdd_DN,cn=IPC_APAC_1_01,cn=DN,cn=Resources,cn=Users,cn=OS 

jemand mir auf diesem helfen kann.

Ich habe versucht, Code unten, aber ich bin nicht in der Lage konstant eingereicht Nummer zu verwenden (e [8]) aufgrund Feldnummer ändern

e = line3.split('","","') 
    print "e" 
    print e 
    e = e[8].replace('"]],','').replace('","','').strip() 
    print "e:" ,e 

Answer 1

Wenn Sie das cn Feld der allerletzte ist garantiert sind, könnten Sie Tun Sie etwas wie:

cnFields = array [-1][-1] 

und dann analysieren, wie Sie es für richtig halten.

Andernfalls müssen Sie das 2d-Array durchlaufen, bis Sie eine Zeichenfolge finden, die mit cn= beginnt.

Answer 2

Sie könnten die Liste reduzieren und dann durchsuchen.

myList = (['one', 'two', ['cn=blahblah', 4, [5],['hi']], [6, [[[7, 'hello']]]]]) 

def flatten(container): 
    for i in container: 
    if isinstance(i, (list,tuple)): 
     for j in flatten(i): 
     yield j 
    else: 
     yield i 

flattenedList = list(flatten(myList)) 

for x in flattenedList: 
    if str(x).startswith('cn='): 
    print(x)
