Why is there no binascii.a2b_binary(bitstr) which returns the binary data
represented by the bit string? Like:
>>> binascii.a2b_binary('0011001100110101')
'35'
perl has pack("B*", "0011001100110101");
What is the python way to do this?
Other fun with strings:
>>> ''.decode('hex')
'33'

Make you class Test new-style:

Hi,
I have a requirement to findout all the classes that are derived from a

This is how I do it currently.

Thank you.

pretty useless in its own way. I have been using python on and off for

Hi,
I have been looking for a good way to convert python code into a
control flow graph.
I know of Python functions that will convert an expression into an
abstract syntax tree (i.e. ast = parser.expr('(x+5)*5') then t =
ast.totuple() then t), but I am not sure how to obtain a CFG.

There are various ways you could do this:
If the number of results won't be too big:
...
for result in sth.fetchall():
print result
If it may be very large:
...
result = sth.fetchone()
while result:
print result
result = sth.fetchone()
Or perhaps nicer:

The FAQ on this subject? ;-)

It's "standard" in C-flavoured languages, certainly, b
Expressions like
>>> 2 + 2
return None, too. I am not certain, but as far as I know this has some
major design reasons. Thus I am certain, that print() will return None
also.

My intuition is that it should be a procedure (i.e. returning None).

I've used Beautiful Soup, and it is a very pythonic way of accessing
the data in the HTML. It is actually very similar to the way you access
the DOM with JS - for example soup.html.body.h1 will give you the first
h1 tag.
There are also various other ways of searching the HTML in XPathish
ways (if

Thanks for the interesting and detailed analysis. In my case I don't
need all possible answers by rather the first "greedy" match. Seems
like there might be some recursive approach.
