  • How to implement a Mutex in Python when using Gtk with PyGTK

    - by Julian
    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?

  • question about python sched schedular.

    - by samy
    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?

  • Exposing members or make them private in Python?

    - by deamon
    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"

  • CAC Client Application Authentication in Python

    - by Präriewolf
    I am building a python application to pull data from a website. The application has to authenticate(HTTPS/SSL) with a CAC card and pin in order to make requests. Am I correct in my assumptions that you can't retrieve the private key from a CAC card, and am therefore stuck using a PKCS #11 Wrapper like PyKCS? Any tips or resources for going about this?

  • Python inter-computer communication.

    - by matt1024
    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?

  • Python shortcuts

    - by lyrae
    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.
