[Tutor] about import statement
Hi Friends, I'm Arun Kumar from India, Just a month ago i started learning programming .learned some basics of python. I'm really enjoying programming in python. I have some doubts in python. When we write programs,we write some import statements at the beginning of the code. how to know that we should import something. How do we know that certain classes are in particular module?

[Tutor] Importing packages
Hi, I'm trying to program with gdata (http://code.google.com/p/gdata-python-client/) using python library.I'm having problem in writing import statements. The source directory content is like this: atom(folder): this folder contains some files with the .py extension gdata (folder):this folder contains some folders and as well as some files with the .py extension. Also each of the folders contain a __init__.py file. I want to use the classes and functions of the gdata and its inner folders' classes and functions. please tell me how write the import statements -- Thank you Arun Kumar http://clicknscroll.blogspot.com ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Importing packages
hi, I am not understanding what you are saying. I included those modules in the sys.path. i want to know how to write the import statement for the modules and packages. I downloaded the gdata client library and extracted it. It contained a scr directory which contained two directories: 1)atom 2)gdata gdata again has some 31 directories and some .py files.These 31 directories contains files with .py extension. Where as the atom directory no further dirrectories. It contained only files with .py extension I want to write the import statementt for the files in gdata directory and also for the files in the 31 directories of the gdata.

Re: [Tutor] Tkinter and python
> python 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.

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___

[Tutor] Writing serialized objects from BaseHTTPServer
Hi Guys,I wrote a simple server using sockets ,the traditional whille True: scoket.accept() approach. This server reads some pickled parameters sent by the client using the cPickle module -> do some processing -> and finally writes a list of tuples, objects using cPickle back to the client output stream ( cPickle.dump).Now I want to replace this server with an HTTP server. Python's BaseHTTPServer basically. I was wondering when using BaseHTTPServer if I want to read/write a serialized object to meet the above behavior how could I achive this using HTTP server ?

[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.
