DispatchWithEvents not working for SQLDMO.Backup
Hi,
I tried the following:
>>> from win32com.client import DispatchWithEvents
>>> class BackupEvent:
... def OnPercentComplete(self, sMessage, nPercent):
... print sMessage, nPercent
>>> oSqlBackup = DispatchWithEvents('SQLDMO.Backup', BackupEvent)
Traceback (most recent call last):
raise ValueError, "This COM object does not support events."
ValueError: This COM object does not support events.
SQLDMO.Backup is a COM object with EVENT, why the error "does not
support events"? I tried the demo of DispatchWithEvents using IExplorer
and it's working, so I think the installation is correct. Is there
anyone facing the same problem?
Thanks,
Chandra

Writing a string.ishex function
Folks, I am new to Python and could not find a function along the lines of string.ishex in Python. There is however, a string.hexdigits constant in the string module. I thought I would enhance the existing modlue but am unsure how I should go about it. Specifically, I have attempted this much: ---cut--- #! /usr/bin/python # -*- coding: utf-8 -*- import string def ishex(string): ishex = False for i in string: if i in string.hexdigits: ishex = True else: ishex = False break return ishex ---cut--- Can someone help me get further along please? Thanks. -- http://mail.python.org/mailman/listinfo/python-list

Thanks to Iain and to you.
One further question: even though it is a single function, is there
any way to convert it into a module? Can existing modules be enhanced
with functions such as these? If not, how may I make my own module,
called, say mystring? At present, I am saving the file as ishex.py and
calling it after declaring
from ishex import ishex
Is there a more elegant way to integrate this function and make it
available to other python scripts using the import mechanism?
Thanks.

Dynamic variable names
Dear Folks, I have read that one should use a dictionary in python to accommodate dynamic variable names. Yet, I am puzzled how to achieve that in my case. Here is what I want to do: 1. The user inputs a number of six-digit hex numbers as a comma-separated list. These numbers represent colours, but the number of colours is not known beforehand. 2. Using these colours in pairs, I am generating image files whose names must be unique. I could use the respective hex numbers for this, but would like to explore generating filenames like colour_1-colour_2.jpg Because I do not know how many colours there would be in advance, I need to generate the colour_n names on the fly. So, my two questions are: 1. How do I do this properly in python? 2. If there is a better scheme than what I have outlined, can someone please point me to a Web link? Thank you.

Sorting a list of lists
Dear Folks, I have lines of values like so: 14, [25, 105, 104] 10, [107, 106, 162] 21, [26, 116, 165] I need to sort them in two ways: (a) By the numeric value of the first column; and (b) by the sum of the elements of the second item in each list, which is a list in itself. At present, I have appended each line into a list L so that I for teh above minimal data, I have a list of lists thus: [[14, [25, 105, 104]], [10, [107, 106, 162]], [21, [26, 116, 165]]] I have tried using (a) sorted(L, key = lambda x:(x[0])) and (b) sorted(L, key = lambda x:(sum(x[1]))) and get the anticipated results for (a) and (b0, at least with the above minimal data set. Is this a sensible way to go about the sorting, or are there better ways of doing it in Python? Also, I am baffled because the above fails obviously when len(L) is about a hundred and I can't figure out why. TIA Chandra -- http://mail.python.org/mailman/listinfo/python-list

It appears that the problem was in the way the data were being read in from a file, than in the sorting itself. Once I fixed that, the results are as expected.

Executing a command from within python using the subprocess module
Dear Folks, I want to execute a command from within python using the subprocess module. Coming from a Perl background, I thought I could use variable interpolation in strings, but found that this is neither supported nor the Python way. Accordingly, I am a little at sea about how to accomplish it. I have stated what I am trying to do in the minimal example below: --- import subprocess width = 5 height = 30 colors = ['#abcdef]', '#456789'] filename = "/tmp/image.png" # I want to get the equivalent of variable interpolation in Perl # so that the command # # convert -size 5x30 gradient:#abcdef-#456789 /tmp/image.png # # is derived from the variables above # and executed by subprocess.call() or subprocess.Popen() # from within Python # # Note that the command "convert" is from the ImageMagick suite # It exists and is executable by the shell; # the remaining values are arguments. # The command has been confirmed to execute correctly. --- Thanks in advance.

Thank you. It works. Now I need to understand why and am able to follow
what you are doing part of the way:
1. Assign default values in the function definition.
2. Store the variables existing in the local namespace in the list lookup.
3. Assert that there are no newlines in the values in lookup converted
to strings. (Why? Is this because of splitlines() later on?)
4. Assemble a string (array?) for the subprocess.call argument using the
format string syntax (section 8.1.3 et seq. of the Python
documentation for 2.6.4). Your example works with default option of
shell=False for subprocess.call().
5. I am unable to decipher how you got to format(**lookup).splitlines())
especially the **prefix part, although I guess that splitlines() is
dishing out the arguments one by one from each line in the
subprocess.call argument.
Any correction of (1) to (4) and an explanation of (5) would be most
appreciated.
All in all, your code is a magnificent example of wrapping the function
within python. This is the first time I have seen something like this.
Thank you very much.

One other question I forgot to ask is this why is there a terminal
backslash in
subprocess.call("""\
Removing the backslash makes the function fail.
I wonder why, because """ is supposed to allow multi-line strings. I am
sorry if this sounds obtuse but that backslash baffles me.

Assuming that the extra right square bracket in 'colors' is a typo,

w = width, h = height, g1 = colors[0], g2 = colors[1], f = filename

Thanks, Alf. It works if I use it so:
subprocess.call(s, shell=True)
and I think that is because s is a single string assembled in almost the
variable interpolation fashion of Perl. It does not work with the
default shell=False argument, presumably because the arguments are not
split into separate strings (something that was horrible to do by hand
using the %s and %() syntax that I had tried out previously).
I think that you and Peter have, between you, shown me two ways of using
subprocess.call(): one with shell=True and the other with shell = False.
Thanks.

Is automatic reload of a module available in Python?
Dear Folks, I am currently developing a python program, let us call it "generic.py", and I am testing out the functions therein by testing them out interactively in the python interpreter by invoking python and doing import generic Once I hit an error, I need to revise my file and reload the module using reload(generic) The difference in syntax between invoking import and reload is really costing me time and patience. Therefore, I would like to ask: 1. Is there a method of auto-reloading a module while developing it and testing it with the interactive python interpreter? 2. Is there a better way of developing a program? Thank you. Chandra -- http://mail.python.org/mailman/listinfo/python-list
Re: Is automatic reload of a module available in Python?
Arnaud Delobelle wrote: Here is a very simple way to improve what you do, which won't require you to change the way you work or to learn a new paradigm: Instead of testing your functions interactively, put your testing code in a file, e.g. 'program_tests.py'. Your can then type python program_tests.py at the shell interactive prompt. To perform the tests again, just re-execute that file. If your tests are divided into different units, you can put these in functions: def test_frobz(): #testing code for frobzation of klops def test_frizz(): #testing code for frizzment of frobzied klops # etc.. So if you want to keep doing interactive tests, you can import program_tests and call whichever testing functions you want. You may even have arguments to those functions to test them with different parameters. I know some people will point at more 'pro' ways of testing but this has the merit of being very straightforward. Then when you move on to more sophisticated techniques, I think you will understand better the motivations behind them. It took me some time to cotton on to exactly what you were saying, but once I grasped it and tried it out, I found it very effective and time-saving.
