I would like to get a list of sub directories in a directory. If I use os.listdir i get a list of directories and files in that . i only want the list of directories in a directory and not the files in it. anyone has an idea regarding this.

Pysqlite storing file as blob example
by rustyhowell＠gmail.com July 31, 2007

July 31, 2007

I'm trying to store binary data in a sqlite database and call into the db using pysqlite 3. What I've got so far is this: import sqlite con = sqlite.connect(DB_PATH) cur = con.cursor() query = """create table t1( ID INTEGER PRIMARY KEY, data BLOB );""" cur.execute(query) con.commit() b = buffer('/path/to/binary/file') query = 'insert into table (ID,data) values (1,?);' result = cur.execute(query,(b)) con.commit() The error message I get is : Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.5/site-packages/sqlite/main.py", line 255, in execute self.rs = self.con.db.execute(SQL % parms) TypeError: not all arguments converted during string formatting I also read about using adapters, but I haven't found any clear info on how to use them. Does anyone have an example of storing binary data (image) in sqlite using pysqlite?

Nasm_with_C++_with_Python
by Jason Ward July 31, 2007

July 31, 2007

I am wanting to write a library in nasm and call it from python. Because python can call c++ libraries. And nasm can be used in c++. So I was wondering how I would go about using nasm in python?

interaction of 'with' and 'yield'
by Neal Becker July 31, 2007

July 31, 2007

I'm wondering if a generator that is within a 'with' scope exits the 'with' when it encounters 'yield'. I would like to use a generator to implement RAII without having to syntactically enclose the code in the 'with' scope, and I am hoping that the the yield does not exit the 'with' scope and release the resource.

Simple question about logging module.
by Gabor Urban July 31, 2007

July 31, 2007

Hullo, I have started to use Python's logging, and got a problem. I have created some loggers and wrote some lines in the log. The problem is, that most of the lines appear doubled in the log, and some lines do not appear at all. Any ideas or comments are wellcome, Gabor Here is the code: import sys import logging l = logging.getLogger('XmlTester') handler = logging.StreamHandler(sys.stderr) l.addHandler(handler) formatter = logging.Formatter("%(name)s %(asctime)s %(filename)s %(lineno)d %(levelname)s %(message)s") handler.setFormatter(formatter) la = logging.getLogger('XmlTester.XmlParser') handler = logging.StreamHandler(sys.stderr) la.addHandler(handler) handler.setFormatter(formatter) lb = logging.getLogger('XmlTester.TestExecutor') handler = logging.StreamHandler(sys.stderr) lb.addHandler(handler) handler.setFormatter(formatter) l.setLevel(logging.DEBUG) la.setLevel(logging.DEBUG) lb.setLevel(logging.DEBUG) l.debug("Start") la.debug("Start la") lb.debug("This debug") lb.info("This started.") l.info("Info written") l.warning("This is a warning") l.error("Error occured") test = "Info.pck" la.info("Hi there!") la.critical("No file named '%s'"%test) l.critical("End of all") Here is the output: XmlTester.XmlParser 2007-07-31 10:34:12,303 plogtest.py 21 DEBUG Start la XmlTester.XmlParser 2007-07-31 10:34:12,303 plogtest.py 21 DEBUG Start la XmlTester.TestExecutor 2007-07-31 10:34:12,319 plogtest.py 22 DEBUG This debug XmlTester.TestExecutor 2007-07-31 10:34:12,319 plogtest.py 22 DEBUG This debug XmlTester.TestExecutor 2007-07-31 10:34:12,319 plogtest.py 23 INFO This started.
