Hello,
how can I see if there is one active mic using python and windows 7?
I want to see if there is one wave in device ready to capture sound!
Thanks in advance :)
I've finally figured out how to create a Python egg and gotten it to work. What do I do with it now? How do I use it? How do I ensure that everything was correctly included? (Simple steps please... not just redirection to another site. I've googled, but it's confusing me, and I was hoping someone could explain it in a couple of simple bullet points or sentences.)
I know that with an InnoDB table, transactions are autocommit, however I understand that to mean for a single statement? For example, I want to check if a user exists in a table, and then if it doesn't, create it. However there lies a race condition. I believe using a transaction prior to doing the select, will ensure that the table remains untouched until the subsequent insert, and the transaction is committed. How can you do this with MySQLdb and Python?
What is a good tool for PDF report generation in Python? I've checked out ReportLab, but it seems to be awfully low-level for what I want to do. My current hunch is to call TeX on the command-line and let it produce the PDF, but if there is something that is easier to work with (and looks professional - We'll send this to customers) I'd very much like a prod in the right direction.
Hello,
My company wants to use Liferay for developing a portal and integrate Alfresco with it for document management.
But both Liferay and Alfresco are Java based and i would like to know if there are any alternatives to Liferay and Alfresco in PHP or Python.
Thank You
ok so I am feeling a little stupid for not knowing this, but a coworker asked so I am asking here: I have written a python algorithm that solves his problem. given x 0 add all numbers together from 1 to x.
def fac(x):
if x > 0:
return x + fac(x - 1)
else:
return 0
fac(10)
55
first what is this type of equation is this and what is the correct way to get this answer as it is clearly easier using some other method?
How do I learn where the source file for a given Python module is installed? (Is the method is different on Windows than Linux?)
(I want to look at the datetime module sources, but I thought I'd ask a more general question.)
Which is the preferred way of defining class properties in Python and why? Is it Ok to use both in one class?
@property
def total(self):
return self.field_1 + self.field_2
or
total = property(lambda self: self.field_1 + self.field_2)
I have the following structure in Python:
letters = [['a', 'b', 'c'], ['p', 'q', 'r', 's'], ['j', 'k', 'l']]
I would like to find all the possible combinations of letters in the order that they currently exist. For the example above this would be:
apj
apk
apl
aqj
aqk
aql
...
csk
csl
This seems like it should be a very simple thing to do but I cannot figure it out.
Hi all,
I am already familiar with python and socket usage and can send strings of text over these. But how would i go about sending, say, an MP3 file?
With the IPTCInfo module under Python (http://snippets.dzone.com/posts/show/768 for more info) it's possible to read, modify and write IPTC info to pictures.
However, if a JPG doesn't already have IPTC information, the module simply raises an exception. It doesn't seem to be able to create and add this metadata information itself.
What alternatives are there? I've googled for the past hour but to no avail whatsoever.
Perhaps by compiling a list of common errors or coding style differences PHP coders make when first starting out with Python, we can help to avoid headaches later on. (Or at least I can :).
I get output files from very old Fortran programs, which look like:
0.81667E+00 -0.12650E+01 -0.69389E-03
0.94381E+00 -0.11985E+01 -0.11502E+00
0.96064E+00 -0.11333E+01 -0.17616E+00
0.10202E+01 -0.12435E+01 -0.93917E-01
0.10026E+01 -0.10904E+01 -0.15108E+00
0.90516E+00 -0.11030E+01 -0.19139E+00
0.98624E+00 -0.11598E+01 -0.22970E+00
Is it possible to read this in Python and convert the numbers to "normal" floats?
Is there a possibility to create any python object that will be not sortable? So that will be an exception when trying to sort a list of that objects?
I created a very simple class, didn't define any comparison methods, but still instances of this class are comparable and thus sortable. Maybe, my class inherits comparison methods from somewhere. But I don't want this behaviour.
I need to get a path to the GIT on Max OS X 10.6 using Python 2.6.1 into script variables. I use this code for that:
r = subprocess.Popen(shlex.split("which git"), stdout=subprocess.PIPE)
print r.stdout.read()
but the problem is that output is empty (I tried stderr too). It works fine with another commands such as pwd or ls.
Can anyone help me with that?
I have been able to read an excel cell value with xlrd using column and row numbers as inputs. Now I need to access the same cell values in some spreadsheets that were saved in .ods format.
So for example, how would I read the value stored in cell E10 from a .ods file from python?
Hello,
How would I pass a Python variable to the Bash shell? It should work like this:
foo="./RetVar.py 42"
Replace the double-quotes with `s
I have tried printing and sys.exiting the result, but to no avail. How would I accomplish my goal?
With a scripting language like python (or php), things are not compiled down to bytecode like in .net or java.
So does this mean that on every request, it has to go through the entire application and parse/compile it? Or at least all the code required for the given call stack?
Hi to all! I have an interesting (to me) problem... There are two threads, one for capturing data from std input and sending it through socket to server, and another one which receives data from blocking socket. So, when there's no reply from server, recv() call waits indefenitely, right? But instead of blocking only its calling thread, it blocks the overall process! Why this thing occurs?
