for example you run some client program, this program communicate with server to recieve data in realtime ... how can i listen to this network traffic and filter / store data in python?
I have a Python app that contains an object structure that the user can manipulate. What I want to do is allow the user to create a file declaring how the object structure should be created.
For example, I would like the user to be able to create the following file:
foo.bar.baz = true
x.y.z = 12
and for my app to then create that object tree automatically. What's the best way to do something like this?
I have read about python sched (task schedular), it works like a cron.
but I have a question :
lets say if i schedule a function to ryn after every 2 hours and in the mean time my system gets shut down, then I again restart the system...did the schedular automatically starts and will run the function after 2 hours? or i have to start that again after shutting down the system?
did sched work like a deamon?
I'm trying to use python to determine if one (small) image is within another (large) image.
Any suggestions before I take myself completely down the wrong path?
I want to be able to take a shortened or non-shortened URL and return its un-shortened form. How can I make a python program to do this?
Additional Clarification:
Case 1: shortened -- unshortened
Case 2: unshortened -- unshortened
e.g. bit.ly/silly in the input array should be google.com in the output array
e.g. google.com in the input array should be google.com in the output array
Thanks for the help!
Hi, I have an application that starts several threads using
gobject.timeout_add(delay, function)
Now in my function I want to test and set on some variable, e.g.
def function(self):
if flag == True:
flag = False
doSomething()
Now to make this threadsafe, I would have to lock the function using some mutex lock.
Is this possible with Gtk? Or can I use the Python Lock objects from threading?
What sort of mime type should I be using to email a .avi file from an automated python script? There are specific ones for audio/images, but not video afaik.
Well i'm learning Python cuz' i think is an awesome and powerful language like C++, perl or C# but is really really easy at same time. I'm using JetBrains' Pycharm and when i define a function it ask me to add a "Documentation String Stub" when i click yes it adds somethin like this:
"""
"""
so the full code of the function is something like this:
def otherFunction(h, w):
"""
"""
hello = h
world = w
full_word = h + ' ' + w
return full_word
I would like to know what these (""" """) symbols means, Thanks.
Ps.Data: Sorry for my bad english :D
I'm curious if their is some python magic I may not know to accomplish a bit of frivolity
given the line:
csvData.append(','.join([line.split(":").strip() for x in L]))
I'm attempting to split a line on :, trim whitespace around it, and join on ,
problem is, since the array is returned from line.split(":"), the
for x in L #<== L doesn't exist!
causes issues since I have no name for the array returned by line.split(":")
So I'm curious if there is a sexy piece of syntax I could use to accomplish this in one shot?
Cheers!

Hi,
What is Python's equivalent of "public static void main(String[] args) { ... }"? I remember having used it in the past and then forgot.
What I'm basically trying to remember is a function which I think included some underscores (__)...
thx
it works fine on 64 bit machines but for some reason will not work on python 2.4.3 on a 32-bit instance.
i get the error
'utf8' codec can't decode bytes in position 76-79: invalid data
for the code
try:
str(sourceresult.sourcename).encode('utf8','replace')
except:
raise Exception( repr(sourceresult.sourcename ) )
it returns 'kazamidori blog\xf9'
i have modified my site.py file to make UTF8 the default encoding, but still doesnt seem to be working.
Hi there,
I have a piece of text that gets handed to me like:
here is line one\n\nhere is line two\n\nhere is line three
What I would like to do is break this string up into three separate variables.
I'm not quite sure how one would go about accomplishing this in python.
Thanks for any help,

I was working with Python with a Linux terminal screen. When I typed:
help(somefunction)
It printed the appropriate output, but then my screen was stuck, and at the bottom of the terminal was "(end)".
How do I get unstuck? Thanks in advance.
I want to send a datetime.datetime object in serialized form from Python using JSON and de-serialize in JavaScript using JSON. What is the best way to do this?
Hi! I am interested in saving and load objects using the pickle module as you can read in a question I asked before:
Python: Errors saving and loading objects with pickle module
Someone commment:
1, In an other way: the error is raise because pickle wanted to load an instance of the class Fruits and search for the class definition where it was defined, but it didn't find it so it raise the error
Now I want to save and load a class definition in order to solve the problem I describe in the question mentioned before.
Thank you so much!
Python is filled with little neat shortcuts.
For example:
self.data = map(lambda x: list(x), data)
and (although not so pretty)
tuple(t[0] for t in self.result if t[0] != 'mysql' and t[0] != 'information_schema')
among countless others.
In the irc channel, they said "too many to know them all".
I think we should list some here, as i love using these shortcuts to shorten & refctor my code. I'm sure this would benefit many.
Is there a general convention about exposing members in Python classes? I know that this is a case of "it depends", but maybe there is a rule of thumb.
Private member:
class Node:
def __init__(self):
self.__childs = []
def add_childs(self, *args):
self.__childs += args
node = Node()
node.add_childs("one", "two")
Public member:
class Node2:
def __init__(self):
self.childs = []
node2 = Node2()
node2.childs += "one", "two"
This whole topic is way out of my depth, so forgive my imprecise question, but I have two computers both connected to one LAN.
What I want is to be able to communicate one string between the two, by running a python script on the first (the host) where the string will originate, and a second on the client computer to retrieve the string.
What is the most efficient way for an inexperienced programmer like me to achieve this?
I have a few questions about python
I've seen many pages like these on Google
http://mail.google.com/support/bin/answer.py?answer=6583
https://www.google.com/adsense/support/bin/topic.py?topic=13488
...that have .py extensions. 1: Are pages like these built on pure python code, but printing out html like print "<div etc..." or like the typical asp,jsp,php type of pages with html pages and embedded python code like:
<html>
<% some python code %>
</html>
2: What is python mainly used for making? windows apps or web or .. ?
3: Are ruby and perl also similar to python?
Hi,
I need to construct an if statement from the data coming from the client as below:
conditions: condition1, condition2, condition3, condition4
logical operators: lo1, lo2, lo3 (Possible values: "and" "or")
Eg.
if condition1 lo1 condition2 lo3 condition4:
# Do something
I can think of eval/exec but not sure how safe they are! Any better approach or alternative?
Appreciate your responses :)
PS: Client-side: Flex, Server-side: Python, over internet
Thanks
Hello everyone,
How can I get the file name and line number in python script.
Exactly the file information we get from an exception traceback. In this case without raising an exception.
