Convert Network Dataset Evaluators from VBA to Python

RachelAlbritton

I am working on converting all of the VBA script evaporators from VBA to Python, and for the life of me I can not get it to work. I understand python, but there is an element to using the script elevator this that I am missing/not understanding.

This is an example of the current VBA that works

Dim val 

val = 0

if(Edge.AttributeValueByName("network_participating)=0) then

val = -1

Based on this, and this, I came up with the code examples below (along with several others not listed) and nothing is working. What am I overlooking?

<SPAN class="keyword token">def</SPAN> <SPAN class="token function">NetworkParticipating</SPAN><SPAN class="punctuation token">(</SPAN>value<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">:</SPAN>
&nbsp; value <SPAN class="operator token">=</SPAN> <SPAN class="number token">0</SPAN>
&nbsp; <SPAN class="keyword token">if</SPAN> Edge<SPAN class="punctuation token">.</SPAN>AttributeValueByName<SPAN class="punctuation token">(</SPAN>value<SPAN class="punctuation token">)</SPAN><SPAN class="operator token">==</SPAN> <SPAN class="number token">0</SPAN><SPAN class="punctuation token">:</SPAN>
&nbsp;&nbsp;&nbsp; value <SPAN class="operator token">=</SPAN> <SPAN class="operator token">-</SPAN><SPAN class="number token">1</SPAN>
&nbsp; <SPAN class="keyword token">return</SPAN> value

Value <SPAN class="operator token">=</SPAN> NetworkParticipating<SPAN class="punctuation token">(</SPAN><SPAN class="string token">'!network_participating!'</SPAN><SPAN class="punctuation token">)</SPAN>

<SPAN class="comment token">##Also tried:</SPAN>

<SPAN class="keyword token">def</SPAN> <SPAN class="token function">NetworkParticipating</SPAN><SPAN class="punctuation token">(</SPAN>value<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">:</SPAN>
&nbsp; restricted <SPAN class="operator token">=</SPAN> <SPAN class="token boolean">False</SPAN>
&nbsp; <SPAN class="keyword token">if</SPAN> value <SPAN class="operator token">=</SPAN> <SPAN class="number token">0</SPAN><SPAN class="punctuation token">:</SPAN>
&nbsp;&nbsp;&nbsp; restricted <SPAN class="operator token">=</SPAN> <SPAN class="token boolean">True</SPAN>
&nbsp; <SPAN class="keyword token">return</SPAN> restricted


<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Going by your original VBA, and what Melinda suggested, try this modification:

def NetworkParticipating(value):
   if Edge.AttributeValueByName( value) == 0:
      return -1
   return 0

Value = NetworkParticipating("network_participating")
