[Tutor] time.mktime(time.gmtime(time tuple from any timezone)) always will be the same ?
Guys, May be a dumb question but I am a bit confused (may be coz working over 24 hours for the last couple days:)). so the question is: No matter which timezone I am in if i say time.gmtime(time.mktime(( datetime.date().timetuple( I will always get the same value. - right ? thx for answering this dumbo question but i need a break! -- Cheers, - A ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] threading.currentThread() always same across request ?
Guys, I have a web application and I want to store an object per request so thta that is available across all classes till end of request. I am planning to write the below code in my entry program which is executed as soon as a request comes: entry.py import threading th = threading.currentThread() th.service = somemod.Service() then in other parts of program whereever I want to use service: th = threading.currentThread() if hasattr(th, 'service'): th.service.call_whatever() I am wondering if I will ever face a problem in this case ? I want to make sure that since the request till the end the same service object is available and it should not collide with any other request. Since it's a web application multilple request may come simutaneously. Is this approach correct ? ___ Tutor maillist - [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] threading.currentThread() always same across request ?
Thx guys. now quick question on the usage of thread local storage. In my case I have the below object model: class Base(object):' def __init__(self): self.__service = None def _GetService(): if not hasattr(threading.currentThread(), 'service'): threading.currentThread().service = Service() self.__service = threading.currentThread().service return self.__service class Child1(Base):' def DoSomething(): service = self._GetService() # use service class Child2(Base):' def DoSomething(): service = self._GetService() # use service The above Child classes are used by a controller: class Controller(object): def process(self): c1 = Child1() c1.DoSomething() ... c2 = Child2() c2.DoSomething() Using the above technique the service is instantiated only one time i.e. as soon as I create the first instance of the Child class abd associated with the current thread for future instantiation of any Child class. Now in this scenario how can I use thread local ? Where do I keep the thread local object as in my case I am instantiating the Child classes ? Using currentThread() always gives me the same thread instance for a given request and I can bypass instantiating the Service class by simply returning the service attribute already attached to the current thread. Any suggestion appreciated! - A On 4/15/07, Kent Johnson [EMAIL PROTECTED] wrote: Andreas Kostyrka wrote: * Kent Johnson [EMAIL PROTECTED] [070414 19:53]: That's a good point. Does anyone know when to prefer threading.local() vs thread attributes? It's design question, I guess: *) if you have thread subclasses, then use thread attributes. *) if you have standard threads, then use thread.local(). The idea is, that it's rude to stick attributes on an object that is not owned by you. Rationale: *) Somebody might decide to make threading.Thread be a new style object with __slots__ = your code breaks. I know, it's unprobably, but if you derive a subclass, you can be at least sure that the object will have a __dict__ ;) If you use threading.local() you can be sure the names you use don't conflict with any attributes of the thread.

Re: [Tutor] Tkinter and python
Hi,You can try: import sys sys.path.append('absolute_path_to_program_dir') import module.pyOr else you can append the path to global PYTHONPATH environment variable and whenever you will type:
python module.py on the command prompt/bash shell the script gets executed.Hope that helps.Thanks,- Arun

Re: [Tutor] Tkinter and python
python module.py on the command prompt/bash shell the script gets executed.Hey Dave,Thanks for correcting me. I should read what I am writing before I hit the send button :). It was a stupid mistake..
Appending path to PYTHONPATH will allow us to import the module in some other Python script without requiring us to do sys.path.apend(). To execute the script from bash what Dave suggests is correct.Also, if you don't want to append path to PYTHONPATH you can also place the module under site-packages directory under Python home directory.

executed.Not true, if I understand you correctly.PYTHONPATH affects wherePython looks for modules to be imported.But if I type thefollowing at the command line:$ python mymodule.py
it is the shell (in my case bash) that looks for mymodule.py, notPython.It analogous to my typing:$ vi mymodule.pyor (trying to avoid a fight between vi and emacs fanatics):$ emacs
mymodule.pyNeither vi nor emacs try to find mymodule.py; the (bash or other)shell does.So perhaps a solution to the problem is to make mymodule.pyexecutable and put it somewhere on your path.Then execute it by
typing at the command line:$ mymodule.pyNow the shell will run it just like any other executable script andit will use Python as the interpreter for that script.How you make the script executable probably depends on which shell
you are using.For bash, you could do the following:1. Insert the following line as the first line of your script: #!/usr/bin/env python2. Change the priveleges of the script to make it executable.
Example: $ chmod u+x mymodule.py3. Put mymodule.py on your path, that is, in a directory that is in your PATH environment variable.Alternatively, add the path to the directory containing
mymodule.py to your PATH environment variable.Dave--Dave Kuhlmanhttp://www.rexx.com/~dkuhlman___
