I just know that it's quite similar to Ruby, and in Ruby, when I print Time.new.to_f, I get a double (float64) that says something like 1292105494.480041, so, I suppose you can find a way to get the same.

Re: [PD] Pd+pachube+python
Thanks guys for yours coments
There was a problem with the datatype (thanks roman and michal), python
script received and sent the data like simbols. To solve the issue i cast
this data to floats in python and now pd patch its working. I think my
solution is really unpolite(sorry iam not a programer) but i can get the
data in to pd numbers boxes. The script is adapted to the specific data
feed, and this data is a vector with tree elements ( ['0',
'2010-12-11T22:11:34.480041Z', '7.6']). First I delate second
elemnt(2010-12-11T22:11:34.480041Z) because i dont know how to cast it and i
dont need the date. There is the python code:
# to receive data
import urllib2
# to send on with OpenSoundControl, OSC
from simpleOSC import *
import time
initOSCClient('127.0.0.1', 57110)
while 1:
data=urllib2.urlopen('
http://api.pachube.com/v2/feeds/2791.csv?key=hereyourownkey') # this data
feed has tree diferents values
for l in data:
d = l.strip().split(,, 2)
del d[1] #this is because this variable was the date and i dont know how
to cast it
var = map(lambda x: float(x), d)
print var
sendOSCMsg('/test/num',var) #
del var[0]
sendOSCMsg('/test/val',var)
time.sleep(5) # wait here some secs

Re: [PD] Pd+pachube+python
Hi Fernando
I wasn't able to successfully run your python script, because I have no
access to the URL you posted:
urllib2.HTTPError: HTTP Error 401: Unauthorized
However, the description of the problem you have did ring a bell. I
remember that once someone had a similar problem. OSC allows to
transport different data types and a '1' can be sent as a string, an int
or a float. Ints and floats are converted by [unpackOSC] to Pd's
floating point number format and strings are converted to Pd's symbols.
I guess what you have here might be a symbolic '1' instead of a numeric
one.
The real fix would be to make sure that numeric values are really sent
as numeric values. That doesn't help if you don't have any control over
the sender. I haven't found yet a nice solution in Pd to convert
symbolic numbers into real floats. You could send all your data over a
[netsend]-[netclient] connection, because then the data is transformed
to FUDI messages and back to Pd messages and thus loses any information
about whether a certain element was numeric or symbolic.
