No name 'ua' in module 'opcua'

[xuplus6493]

Hello,
I have install opcua
but when I use this code by Visual Code (Python 3.8.2 32bit)
from opcua import Client,ua
I get the problem

No name 'ua' in module 'opcua' (no-name-in-module)

How can I fix it ?

if u use pythons builtin IDE -> "idle" does it also blame that there is no "ua"

I want to write Tag (kepware server)
the same code is working in another computer

[AndreasHeine]

yeah because ua.VariantType.Double is missing... then you'll get BadTypeMismatch !!!

you will not like my answer...

from opcua import ua

opcua datatypes and python datatypes are different so you have to be specific what opcuatype you want to set!

"var = 1" is an Python int => OPCUA Int 64
