Re: Anything equivalent to cassert in C++?

Actually, if an assert statement is never raised in production code
irrespective of the condition (even in case of malicious inputs), it is
the correct use of assert statement. The difficulty is in proving that
it is impossible to raise the assert. In most cases it is impossible to
prove and we just turn off assert when we're quite confident that it is

Would never occur ? You can't use 'would' and 'never' in the same
sentence. That is the kind of concect that make (to me) asserts diffcult
to use.
I personally never use asserts in python, cause I will end up handling
with asserts what I should in fact handle properly in what you call the
production code.

I looked at this - I did some google search and it seems to me a dead

I thought that some of you is aware of embedded system development
with help of python.
It would be nice to have not just JTAG, BDM support and even data
logging, recording, display and post processing - similar to features

You should be very careful not to put unit tests in asserts because that
prevents you from testing your application under optimization.

Re: How do I correctly download Wikipedia pages?

2009-11-26T17:38:00Z

On occasion I use a program under Debian Linux
called wikipedia2text that is very handy
for downloading wikipedia pages as plain text files ....
Description: displays Wikipedia articles on the command line

This script fetches Wikipedia articles (currently supports
around 30 Wikipedia languages) and displays them as plain text

The code is assuming that the lines are all at least 19 characters long;
if a line is shorter then there's no position 19!
Try checking the line length too:
if len(L) >= 19 and L[19] == 'W':
Alternatively:
if L[19 : 20] == 'W':
(If the line is too short then L[19 : 20] will return ''.)

On line 68 you have a string literal immediately followed by a tuple, so
it looks like you're trying to call a string, hence the exception. Put a
comma between the string literal and the tuple.

Absolutely! That's the whole point. If you can't construct the class,
you *should* raise an error. The only other workable option is to leave
the target set to None, which is uglier because you don't track the
error.

While I may disagree with Kutlu on some points[1], it's clear that the
key to handling huge traffic is the ability to scale up. So better to
avoid solutions that make it hard - or impossible - to setup load

Low level usage via ctypes looked like this:
import ctypes
tbdml = ctypes.windll.LoadLibrary("tbd ml.dll")
tbdml.tbdml_init() # returns number of devices
tbdml.tbdml_open(0)
tbdml.tbdml_target_sync() # returns 0 on success
tbdml.tbdml_write_byte(0x0,2) # set port

Don't know about JTAG, but I've successfully used a TBDML interface from

Basically, any BDM or JTAG interface should have a DLL as driver which
you can import using ctypes.
