  PYKX not allowing to change Python attribute of Q Object

  Posted by Nachofest on May 17, 2025 at 12:44 pm

  I am trying to do the following:

  “`</p><p>import pykx</p><p>old=”:host:Port:user:old”</p><p>pykx.q.my_handle=old</p><p>new=”:host:Port:user:new”</p><p>pykx.q.my_handle=new</p><p>“`

  The above works as expected. If I then try to access vía Python or directly from Q memory I would get the string in the new var.

  “`</p><p>print(pykx.q.my_handle)</p><p>print(pykx.q(‘string .my_handle’))</p><p>“`

  **However**, if I access the attribute (for any reason) before setting It to new value then something *weird* happens:

  “`</p><p>import pykx</p><p>old=”:host:Port:user:old”</p><p>pykx.q.my_handle=old</p><p>print(f”my handled: {pykx.q.my_handle}”)</p><p>new=”:host:Port:user:new”</p><p>pykx.q.my_handle=new</p><p>#prints old</p><p>print(pykx.q.my_handle)</p><p>#prints new</p><p>print(pykx.q(“string .my_handle”))</p><p>“`

  Anyone knows why? **Note** my handled has to be refreshed with new password/token whenever needed, in theory I vannot think about a use cas

  Copying answer from SO thread for reference:

  https://stackoverflow.com/questions/79626532/pykx-not-allowing-to-change-python-attribute

  . Notation is for the context interface and namespaces

  pykx.q.myhandles.a = 1
  pykx.q.myhandles.b = 2
  

  For variables in root namespace use []

  pykx.q['handle_a'] = 1
  pykx.q['handle_b'] = 2
