Request DDE data using Python

Question

I'm trying to request DDE data without success. Where's my code:

# DDE code
# LibreOffice equivalent of this code is: =DDE("profitchart"; "cot"; "DI1F23.ABE"; 1)

import win32ui
import dde


server = dde.CreateServer()
server.Create("profitchart")
conversation = dde.CreateConversation(server)
conversation.ConnectTo("profitchart", "cot")

requested_data = conversation.Request("DI1F23.ABE")

print(requested_data)




dde.error: Request failed

It's a dumb question, but I can't figure out...

I'm using Python 3.5
