RTD client in Python

Question

my goal is to get the updates of an rtd server in python

I've following call in excel which is working:

=RTD("xrtd.xrtd";;"EUCA")

For python I've found following client library: https://github.com/brotchie/pyrtd/blob/master/rtd/client.py

I tried to get a simple example where I can connect to the server

import sys
sys.path.append(".")
from client import RTDClient 
name = "xrtd.xrtd"

try:
    client = RTDClient(name)
    client.connect(False)
    client.register_topic('EUCA')

except Exception as identifier:
    print(str(name) + " error : " + str(identifier))

My first problem was that I've used 64bit python, but after I solved this I receive following exception from the connect():

xrtd.xrtd error : This COM object can not automate the makepy process

please run makepy manually for this object

I've no idea what I've to do now. I've python experience but no experience with COM Objects

To whom so ever it may concern, the library is written in `python2` — fireball.1, Jul 19 '20 at 08:19

Try this

import pythoncom
from rtd import RTDClient

if __name__ == '__main__':
    time = RTDClient('xrtd.xrtd')
    time.connect()
    time.register_topic('EUCA')

    while 1:
        pythoncom.PumpWaitingMessages()

        if time.update():
            print time.get('EUCA')

Thank you for the answer, but this isn't the problem. I got an exception from the connect function – Hunk Jul 19 '20 at 07:30
