hex notation funtion
Hi, Is there a builtin function that will enable me to display the hex notation of a given binary string? (example below) many thanks Tertius () 02 11 00 00 46 5A 1A 82 02 11 00 39 36 39 33 39 FZ.96939 0016(0010) 36 39 33 00 0A 30 33 37 34 34 39 35 38 25 DD 01 693..03744958%.. -- http://mail.python.org/mailman/listinfo/python-list

Re: exec function

I'm a newbie to pthyon and I am creating an app with wxPython.
I have 7 tables (more on the way... they are feed from a database) that
need to be formatted in a certain way (DataTable() does this) and I am
just looking for a cleaner way to pass all of the Grids (grid_1,
grid_2, etc) through the same function.
I am currently doing this (ugly, but it works):
for i in tables.keys():
if datadict.has_key(i):
t = tables.get(i)
d = datadict.get(i)
r = rowdata.get(i)
exec('self.frame.%s.SetTable(DataTable(d, r[0]), True)' % t)
It works (slowly) and I have read that exec is very slow and bad
form...Can any one give me any pointers to clean this mess up?
frame = a wx.Frame (another file which is imported).
Thanks,

date diff calc
Hi,
Is there a more pythonic way to write or do a date difference
calculation? I have as input two date fields in the form '-MM-DD'
TIA
Terius
from datetime import date
bdl = '2004-11-25'.split('-')
edl = '2004-11-30'.split('-')
bd = date(int(bdl[0]), int(bdl[1]), int(bdl[2]))
ed = date(int(edl[0]), int(edl[1]), int(edl[2]))
print ed , '-', bd , '=', (ed-bd).days

However as nice as it is, there are many frameworks and business applications that is written and packaged in Java (i.e. X25 comms Libraries, log4J *before* python brought out logging) _OR_ has a Java remote interface that must be accessed (EJB /JMS / RMI etc...) _OR_ has a library you prefer to use of over the python implementation (not a lot of those). Jython allows one to use these packages using ones language of choice :) Thanks Jython -- http://mail.python.org/mailman/listinfo/python-list
Static parameter count

Many TIA T # L = [1,2,3,4,5,6, etc] # L can contain 'n' elements # fmt is made up to each particular specification if len(L) == 0: return '' elif len(L) == 1: return struct.pack(fmt,L[0] ) elif len(L) == 2: return struct.pack(fmt,L[0] , L[1]) elif len(L) == 3: return struct.pack(fmt,L[0] , L[1], L[2]) elif len(L) == 4: return struct.pack(fmt,L[0] , L[1], L[2], L[3]) elif len(L) == 5: return struct.pack(fmt,L[0] , L[1], L[2], L[3], L[4]) elif len(L) == 6: return struct.pack(fmt,L[0] , L[1], L[2], L[3], L[4], L[5]) # etc... etc... etc ... -- http://mail.python.org/mailman/listinfo/python-list

inter threading info
Hi All, Q: Is it possible for a thread on SocketServer.ThreadingTCPServer to get the socket info of *other* open thread/s and use that info to send data to the accepting client? I wrote a socketserver using SocketServer.ThreadingTCPServer. A client is connected to the server and expects multiple request/responses. (Not sure about the terminology but the client connects and then stay connected for a while.) I need to create a client that can connect to server and then determine how many other clients are connected, what the socket info is (ifile/ofile) and then send and receive specific data to those clients. TIA T -- http://mail.python.org/mailman/listinfo/python-list

I was thinking of a dict or list _global_ to the StreamRequestHandler.handle() method. That way I can pass the info on with every new connection where the server will have access to it. > > > (ifile/ofile) and then send and receive specific data to those clients. > > ifile/ofile are local to the server process so you cannot use them to > send data from one client to another client.

I'm busy developing a test/mock harness for a financial switch. Currently it caters only for messages from the client to the harness and then back. I need to add functionality that when an _external_ message arrives, the switch can determine which client it needs to send the data to.
