Dear Team,
I want to connect to Bloomberg with Python 3.2.
Looking on internet I found couple of programs written by diverse authors. I
implemented by It does not work.
I followed the following steps, I included the python code and the error
messages:
I will really appreciate if you could help me.
(Please forward to the right person).
Regards,
Michel
Step 1 : Install Bloomberg Desktop API v3 from API <GO> download page (file is
contained in DAPI_2.zip)
Step 2 : Download and install : ActiveState Python x86 (Key point : not the
64-bit version)
Step 3 : (For safety) :
Start menu > start > all programmes > bloomberg > api environment diagnostics >
start diagnostic tool
repair if needed. Ignore settings errors.
Step 4 : In any directory, run the minimal.py file given below :
python minimal.py
-------------- minimal.py --------------
import win32com.client
from pythoncom import PumpWaitingMessages
from time import time
class EventHandler:
def OnProcessEvent(self, result)
event = win32com.client.gencache.EnsureDispatch(result)
iterator = event.CreateMessageIterator()
while iterator.Next():
print "EventType[%d] -> %s" % (event.EventType,
iterator.Message.MessageTypeAsString,)
session = win32com.client.DispatchWithEvents('blpapicom.Session.1' ,
EventHandler)
## Each one of these gives rise to another message
session.Start()
started = session.OpenService('//blp/mktdata')
endTime = time() + 2
while True:
PumpWaitingMessages()
if endTime < time():
break
Error Message:
