Is there any Python ORM such as SQLAlchemy that would allow this? ...

This is Python >=2.6. >>> urllib.urlretrieve(url[, filename[, reporthook[, data]]]) However, urlretrieve is so dumb that it ...

The application requires embedding of python to run plug-ins, I've successfully embedded using the Cygwin python libraries and was able to run simple python files as part of the program. However, the python files now require the use of a windows GUI framework (wxPython), ...

I'd like to be able to write a function that looks and works something like this: response = urllib2.urlopen("...
This is a rather useless assertion error; it does not tell the values of the expression involved (assume constants used are actually variable names): $ python -c "assert 6-(3*2)" [...] AssertionError Is there a better assert implementation in Python that is more fancy? It must not introduce additional overhead over execution (except ...

I need to simulate multiple embedded server devices that are typically used for motor control. In real life, there can be multiple servers on the network and our desktop software acts as a client to all the motor servers simultaneously.

A simple problem, really: you have one billion (1e+9) unsigned 32-bit integers stored as decimal ASCII strings in a TSV (tab-separated values) file. Conversion using int() is horribly slow compared to other tools working on the same dataset. Why? And more importantly: how to make it faster? Therefore the question: what is the fastest wa...

Pyzor uses UDP/IP as the communication protocol. We recently switched the public server to a new machine, and started getting reports of many timeouts. I discovered that I could fix the problem if I changed the IP that was queried from eth0:1 to eth0. I can reproduce this problem with a simple example: This is the server code: #! /u...
