Python 2.5 to 2.7: #a.py: def foo(): pass #b.py from a import foo foo() From foo(), I'd like to know that it has benn called in the "b" module.

Hey all I wanted to know how is it possible in django to bind an already uploaded file (stored in the file system of server) to a Model FileField. This way I want to have my edit page of that model to prepopulate the FileField with this file. Thanks ...
Python elementTree seems unusable with namespaces. What are my alternatives? BeautifulSoup is pretty rubbish with namespaces too. I don't want to strip them out. Examples of how a particular python library gets namespaced elements and their collections are all +1. Edit: Could you provide code to deal with this real world use-case using...
I have a need, for a python script I'm creating, to first get just the PID of a process (based on its name) and then to get from that process, usings its PID, its time duration, which, from the printout below, would be "00:00:00" root 5686 1 0 Sep23 ? 00:00:00 process-name I am using this to get just the PID, by the p...
I've built a product database that is divided in 3 parts. And each part has a "sub" part containing labels. But the more I work with it the more unstable it feels. And each addition I make it takes more and more code to get it to work. A product is built of parts, and each part is of a type. Each product, part and type has a label. And...
I have been looking for a while a python module/API that does something I believe is quite simple: Read an XML file Add/Edit/Remove entries So far I've found several snippets that interface with complicated object oriented databases, but nothing dead simple as: xml = etree.parse ('file.xml') xml.add(xpath, new_node(attrs)) xml.remo...

The top events pane is a wx.grid.Grid. The bottom data pane is a wx.Panel that contains a wx.grid.Grid. The middle plot pane is a wx.Panel containing an enthought chaco p...
I have two python scripts that have to run simultaneously because they interact with each other. One script is a 'server' script running locally and the other is client script that connects to it via a socket. Normally I just open a couple terminal tabs and run the server script in one and the client in the other. After starting and stop...
I want to implement a userland command that will take one of its arguments (path) and change the directory to that dir. After the program completion I would like the shell to be in that directory. So I want to implement cd command, but with external program. Can it be done in a python script or I have to write bash wrapper? Example: ...

can anyone, please, explain to me in very simple terms what "method" is in Python? The thing is in many Python tutorials for beginners this word is used in such way as if the beginner already knew what method is in the context of Python. While I am of course familiar with the general meaning of this word, I have no clue what this term m...
I'm trying to take a python class (in IronPython), apply it to some data and display it in a grid. The results of the functions become columns on the grid, and I would like the order of the functions to be the order of the columns. Is there a way to determine the order of python functions of a class in the order they were declared in t...

Thanks! ...
No idea why this error is popping up. Here are the models I created - from django.db import models from django.contrib.auth.models import User class Shows(models.Model): showid= models.CharField(max_length=10, unique=True, db_index=True) name = models.CharField(max_length=256, db_index=True) aka = models.CharField(max_le...
I've written a class whose .__hash__() implementation takes a long time to execute. I've been thinking to cache its hash, and store it in a variable like ._hash so the .__hash__() method would simply return ._hash. (Which will be computed either at the end of the .__init__() or the first time .__hash__() is called.) My reasoning was: "T...
I have some data that lends itself to representation as a value and a comparison function, (val, f), so another value can be checked against it by seeing if f(val, another) is True. That's easy. Some of them just need >, <, or == as f, however, and I can't find a clean way of using them; I end up writing things like ScorePoint(60, la...
I'm attempting to create python module for getting network parameters. I'm using ctypes and has some problems. Function __getInterfaces_win2k() works with python 2.5 and 2.6, but doesn't work with python 2.7 (Unhandled exception at 0x1e001759 in python.exe: 0xC0000005: Access violation reading location 0x00000010.)
