@Robert: Thanks.  I'll study this to get a better idea where I went wrong!

@Julius: That works.  Showing my revised code:

Method AddContentTypeCode5(pContentStream As %Stream.GlobalCharacter, Output pNewContentStream As %Stream.GlobalCharacter) As %Status
Set tStatus = $$$OK
try {
Set pNewContentStream=##class(%GlobalCharacterStream).%New()
Set tLocatorString = "<ns2:Description>"
Set tInsertPoint = pContentStream.FindAt(1,tLocatorString,.tStr,0)-1
Do pContentStream.Rewind()
Do pNewContentStream.Write(pContentStream.Read(tInsertPoint)), pNewContentStream.Write(..ContentTypeCodeInsertable), pNewContentStream.Write(pContentStream.Read(pContentStream.Size-tInsertPoint))
catch ex {
Set tStatus = ex.AsStatus()
Quit tStatus

This documentation shows how to connect and interact with IRIS using Python.  Following this worked for me:


Using port 1972 per the example worked in my case but your installation may vary.  It requires Python 3 (3.4+).  When you download the Intersystems wheel file, make sure that the filename remains unchanged otherwise pip won't be able to install it.


Thanks Robert!  I got it working.  I just needed to set my port correctly. It was incorrectly set to 58772 which is what we use for making http connections.  I changed it to 1972 and it worked.
