Layer Label Toggle

VishalShah2

I am trying to write a python script for a tool that lets you toggle the labels for specific feature classes using Boolean values. My question is how can I get the labels to turn on or off? I've seen examples of people using the variable.showLabels = True to get their labels to display but for me it did not work. Any help is greatly appreciated.

<SPAN class="keyword token">if</SPAN> <SPAN class="punctuation token">(</SPAN>turnLabelsOnOff <SPAN class="operator token">==</SPAN> <SPAN class="token boolean">True</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="operator token">and</SPAN> <SPAN class="punctuation token">(</SPAN>layer <SPAN class="keyword token">in</SPAN> layerList<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">:</SPAN>
&nbsp;&nbsp;&nbsp; layer<SPAN class="punctuation token">.</SPAN>showLabels <SPAN class="operator token">=</SPAN> <SPAN class="token boolean">True</SPAN>

<SPAN class="keyword token">if</SPAN> <SPAN class="punctuation token">(</SPAN>turnLabelsOnOff <SPAN class="operator token">==</SPAN> <SPAN class="token boolean">False</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="operator token">and</SPAN> <SPAN class="punctuation token">(</SPAN>layer <SPAN class="keyword token">in</SPAN> layerList<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">:</SPAN>
&nbsp;&nbsp;&nbsp; layer<SPAN class="punctuation token">.</SPAN>showLabels <SPAN class="operator token">=</SPAN> <SPAN class="token boolean">False</SPAN>

&nbsp;&nbsp;&nbsp; layer<SPAN class="punctuation token">.</SPAN>showLabels <SPAN class="operator token">=</SPAN> <SPAN class="token boolean">True</SPAN>

Vishal,

Instead of referencing the variables via their quoted name, reference the layers as such:

x <SPAN class="operator token">=</SPAN> arcpy<SPAN class="punctuation token">.</SPAN>mapping<SPAN class="punctuation token">.</SPAN>ListLayers<SPAN class="punctuation token">(</SPAN>mxd<SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"X"</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">[</SPAN><SPAN class="number token">0</SPAN><SPAN class="punctuation token">]</SPAN>
y <SPAN class="operator token">=</SPAN> arcpy<SPAN class="punctuation token">.</SPAN>mapping<SPAN class="punctuation token">.</SPAN>ListLayers<SPAN class="punctuation token">(</SPAN>mxd<SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"Y"</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">[</SPAN><SPAN class="number token">0</SPAN><SPAN class="punctuation token">]</SPAN>
layerList <SPAN class="operator token">=</SPAN> <SPAN class="punctuation token">[</SPAN>x<SPAN class="punctuation token">,</SPAN> y<SPAN class="punctuation token">]</SPAN>‍‍‍‍‍‍‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

One variation of the code that you have posted before will work as well now that the variables are being referenced correctly. 

<SPAN class="keyword token">for</SPAN> lyr <SPAN class="keyword token">in</SPAN> arcpy<SPAN class="punctuation token">.</SPAN>mapping<SPAN class="punctuation token">.</SPAN>ListLayers<SPAN class="punctuation token">(</SPAN>mxd<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">:</SPAN>
&nbsp;&nbsp;&nbsp; <SPAN class="keyword token">if</SPAN> lyr<SPAN class="punctuation token">.</SPAN>supports<SPAN class="punctuation token">(</SPAN><SPAN class="string token">"LABELCLASSES"</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">:</SPAN>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <SPAN class="keyword token">if</SPAN> lyr <SPAN class="keyword token">in</SPAN> layerList<SPAN class="punctuation token">:</SPAN>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; lyr<SPAN class="punctuation token">.</SPAN>showLabels <SPAN class="operator token">=</SPAN> <SPAN class="token boolean">False</SPAN>‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

You'll want to throw in your toggle variable as well, but that is just an extra if statement line just before the showLabels action.
