Comment acceder a un champ de bdd par son nom, (ou acces a un tuplede tuples)

bonjour

je me connecte à une base de données interbase/firebird en utilisant,
KinterbasDB
http://kinterbasdb.sourceforge.net/ pour ceux que ca interesse

mais je pense que le probleme est le meme quel que soit la bdd

j'aimerais acceder a un champs par sont nom plutot que par son index
dans le record en cours, comme je fais maintenent

la prop description du curseur renvoye le tuple de tuple suivant
(('PATIENTID', <type 'str'>, 180, 180, 0, 0, True),
('ORIGINALPATIE NTID', <type 'str'>, 60, 60, 0, 0, True), ('CENTERID',
<type 'int'>, 11, 4, 0, 0, True), ('NAME', <type 'str'>, 452, 452, 0, 0,
True), ('FIRSTNAME', <type 'str'>, 452, 452, 0, 0, True), ('BIRTH',
<type 'int'>, 6, 2, 0, 0, True), ('SEXE', <type 'int'>, 6, 2, 0, 0,
True), ('ENTRYDATE', <type 'DateTime'>, 10, 4, 0, 0, True), ('COMMENTS',
<type 'str'>, 0, 8, 0, 2, True), ('LASTMODIFDATE ', <type 'DateTime'>,
10, 4, 0, 0, True), ('DEP', <type 'int'>, 6, 2, 0, 0, True),
('QUESTIOID', <type 'int'>, 11, 4, 0, 0, True), ('CREADATE', <type
'DateTime'>, 22, 8, 0, 0, True))

le row courant est lui un tuple simple:
('02-0000', None, 2, None, None, 1961, 1, <DateTime object for
'2002-06-16 00:00:00.00' at 90c860>, 'sevrage effectu\xe9\x00 \x00',
<DateTime object for '2002-07-16 00:00:00.00' at 932f20>, None, 520,
<DateTime object for '2004-07-05 00:00:00.00' at 91f4e0>)

comment, par exemple, acceder au 3em element du tuple (en l'occurence le
nombre 2) en utilisant le nom CENTERID qui est le premier element du
3eme element du tuple qui decrit la strucure ?

j'espere que je me suis fais comprendre

merci d'avance...

Salut Richard,

je fais quelque-chose de tres semblable. Mon idee est la suivante
(attention, je tape tout de tete et je te laisse le soin de tester
toi-meme):

# d'abord il faut extraire une list de tous les noms:
names = [ x[0] for x in cursor_descript ion ]

# ensuite tu bricoles un dictionnaire avec le row courant:
row = dict(zip(names, current_row))

# tu peux maintenant faire les acces suivants:
center_id = row["CENTERID"]
first_name = row["FIRSTNAME"]
# etc...

Un derniere remarque: la langue officielle de comp.lang.pytho n est
l'anglais. Tu auras donc beaucoup plus de succes si tu traduis tes
messages avant de les envoyer...

Bonne chance,

Jan

Please comment on the new PEP for reverse iteration methods. Basically, the idea looks like this: for i in xrange(10).iter_backwards(): # 9,8,7,6,5,4,3,2,1,0 <do something with i> The HTML version is much more readable than the ReST version. See: http://www.python.org/peps/pep-0322.html

The core concept is that clarity comes from specifying a sequence in a forward direction and...

Tuples are defined with regards to parentheses ()'s as everyone knows. This causes confusion for 1 item tuples since (5) can be interpreted as a tuple OR as the number 5 in a mathematical expression such as x = (5) * (4+6). Wouldn't it have been better to define tuples with <>'s or {}'s or something else to avoid this confusion?? Perhaps ()'s are a good idea for some other reason I don't know?

I was looking for a function or method that would return the index to the first matching element in a list. Coming from a C++ STL background, I thought it might be called "find". My first stop was the Sequence Types page of the Library Reference (http://docs.python.org/lib/typesseq.html); it wasn't there. A search of the Library Reference's index seemed to confirm that the function did not exist. A little later I realized it might be called...

Please help me think of an example where immutable tuples are essential. It seems that everywhere a tuple is used one could just as easily use a list instead. chris
