Hey,  
Apologies it took me a while to respond, thank you so much for your help.  
For future reference to those who stumble on this post I would like to elaborate on the solution.  
@lassoan thank you for the suggestion of improving on the string formatting. Use of

> “\n” and “\t”

within the string was not a problem. Although for future reference it is good to know that I can separate commands inline with semicolon “;”  
The real problem was that I was trying to set

> self.host\_port

by accessing

> slicer.util.getModule(‘BlenderMonitor’).widgetRepresentation().self().[widget init var]

Reviewing @lassoan suggestion, widget class functions are more appropriately accessed by the

> slicer.util.getModuleWidget().[widget class method] ()

method. When I switched to getModuleWidget() and wrapped self.host\_port variable in the self.connect\_to\_blender() method I was able to pass and set self.host\_port on widget startup.

TL;DR @lassoan code suggestions worked well, use of semicolon was not necessary and use of \n and \t in string formatting is acceptable when --python-code
