Re: sqlite empty inserts

I forgot to mention that i was creating a view just before this i.e sql="create view %s as %s" % (foldername, query) # self.cursor.execute(sql) self.cursor.execute(sql) Now if i remove this, the insert code works fine. Regards Saptarshi -- http://mail.python.org/mailman/listinfo/pytho

Yes, that could be the case. Browsing through hadoop's source, i see stdin in the above code is reading from piped Java DataOutputStream. I read of a libray on the net Javadata.py that reads this but it has disappeared. What is involved in reading from a Dataoutputstream? Thank you Sapsi --

Python,SWIG and libjvm

Hello, I'm not sure if this the correct list but here goes (and sorry for the noise). I've been attempting to wrap python around libhdfs. So far so good (i've attached the SWIG template at the end). The compilation works without errors and the shared objects do have references to all the functions.

Sets in Python

Hello, I recently tried using the set function in Python and was surprised to find that a=[ 1, 2,3, [1,2] ] doesn't work with 'set', throwing TyperError (unhashable exception). I found out that this is because lists can't be hashed. So,this implies 'a' cannot be a set in python which i think is

Using struct timeval in python

Hi, I am using a library (pcapy) that returns a timeval object T= (seconds,microseconds) where microseconds is always < 1e6. Is there a Python class that can handle timeval structs? Specifically, I wish to subtract two T (defined above) objects, taking into account the large values of T[0] and T[1]

Hi, I managed to create a python class and instantiate that from my Objective C Cocoa App (its not a python app). Essentially, i made two classes in IB and then another class(ogle) with outlets for these two. Now here is the implementation for ogle.m -(void)awakeFromNib { NSNumber *n=[NSNumber
