How to call application in the background with subprocess.call
Hi, I'd like to call an external application (firefox) from a python program (a PyQT GUI), but I want the external application to run in the background, I mean I do not want my python calling program to wait till the external subprocess terminates. I've tried this: call([firefox, http://www.python.org;]) but my PyQT interface freezes until I terminate Firefox. Is there any parameter I need to use with call so that the python calling program doesn't wait for the termination of the subprocess? Many thanks -- http://mail.python.org/mailman/listinfo/python-list
Re-enabling a logger
Hi, I'm using the logging module. At one point in my code I disable logging like this: logging.disable(logging.INFO) But how can I enable the logging again further on? I've tried the following, which doesn't work for re-enabling the logger: my_logger.setLevel(logging.INFO) I've also tried to disable the logger by doin this: my_logger.setLevel(logging.NOTSET) and then re-enabling like this: my_logger.setLevel(logging.INFO) But that doesnt work either. Can you tell me how to re-enable the logging? Many thanks. -- http://mail.python.org/mailman/listinfo/python-list
logger module : Question about log message format
Hi,
I've created a logger like this:
LOG_FILENAME = 'test.txt'
fh=logging.FileHandler(LOG_FILENAME,'w')
logger1 = logging.getLogger('myLogger1')
logger1.addHandler(fh)
logger1.setLevel(logging.INFO)
logger1.info('message from logger1')
and was hoping to get log messages in this format in my log file:
:INFO:myLogger1:message from logger1
instead I just get a plain message like this:
message from logger1
Do you know why?
Many thanks.

Question about apply
Hi,
I'm using apply to pass keyword arguments as a dictionary to a funcion at
runtime (which keyword arguments to pass is only known at runtime)
apply is very handy for this, because it takes a dictionary of keyword
arguments directly
def f1(a=None,b=None,c=None):
pass
kw={'a':1}
apply(f1,[],kw)
But I read in the doc that apply is deprecated.
What is the non-deprecated way of doing this?
Many thanks

Use the double-star syntax:
f1(**kw)

Re: How to document Python code properly for Pydoc

Also includes the description of the return value. ''' pass pydoc doesn't recognize any special markups.

Retrieving column values by column name with MySQLdb
Hi,
Is there a way of retrieving the value of columns in the rows returned by
fetchall, by column name instead of index on the row?
Code Snippet:
query=select * from employees
db=MySQLdb.connect(host=host,user=user,passwd=passwd,db=database)
cursor = db.cursor ()
cursor.execute (query)
rows = cursor.fetchall ()
for row in rows:
print row[0]
Instead of specifying the index of the row to retrieve the first column
(row[0]), I'd like to retrieve the value of the first column by column name.
Something like row.get('employee_id')
Is something of the sort possible with Mysqdb?
Thanks very much.

Accessing files in a directory which is a shortcut link (Windows)
Hi, I'd like to process files in a directory which is in fact a short cut link to another directory (under windows XP). If the path to the directory is for instance called c:\test. I have tried both following code snipets for printing all names of files in the directory: ++ snippet 1++ for filename in glob.glob( os.path.join(r'c:\test', '*') ): print filename ++ snippet 2++ for filename in glob.glob( os.path.join(r'c:\test.lnk', '*') ): print filename Neither solution works.

Using ascii numbers in regular expression
Hi, How can I use the ascii number of a character in a regular expression (module re) instead of the character itself? Thanks very much -- http://mail.python.org/mailman/listinfo/python-list
Re: Using ascii numbers in regular expression
Thanks very much for your reply.
What I mean is that I would like to use the ascii number in a regular
expression pattern.
For instance, if I want to substitute the occurrences of character 'a' for
the character 'b' in a string, instead of doing this:
re.subn('a','b','')
I'd like to specify the ascii number of a (which is 97)
I tried converting 97 to hexadecimal (with hex()) and tried this
re.subn(''\0x61,'b','')
but it doesnt work.
I need this because I'm working on non printable characters.
Thanks a lot

I refer you to the chr() and ord() built-in functions, which can
certainly be used to solve your problem, though they are not
regex-specific in application.

Using ZSI Soap libraries from behind a proxy-based firewall
Hi I'm trying to build a simple soap client using the ZSI library. My python script operates from behind a proxy-based firewall.

Retrieving http headers from HTTPConnection object

getpixel with Python Imaging Library
Hi, I read that the getpixel function of the PIL library is relatively slow. Which alternative is therefore faster and more efficient, accesing the result of getdata() as a flat list or using the function load(), and accessing pixels through the resulting 2-dimensional array?
