arcpy.mapping.RemoveLayer question

cwh

Hello all,

I have a function that looks like:

<SPAN class="keyword token">def</SPAN> <SPAN class="token function">RemoveLayers</SPAN><SPAN class="punctuation token">(</SPAN>mxd<SPAN class="punctuation token">,</SPAN>layers<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">:</SPAN>

    <SPAN class="keyword token">del</SPAN> mxd‍‍‍‍‍‍‍‍‍‍‍‍
‍‍‍‍‍‍‍‍‍‍‍‍

The line being used to call the function is:

RemoveLayers<SPAN class="punctuation token">(</SPAN>ProposedMxd<SPAN class="punctuation token">,</SPAN><SPAN class="string token">"'OP_SITE_MNT','LU_BOUNDARY_MNT - OUTLINE','LU_BOUNDARY_MNT - WHITE FILLED','COMM_BOUNDARY_MNT'"</SPAN><SPAN class="punctuation token">)</SPAN>‍
<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

What I see as output is:

Any ideas as to why these 2 layers in red are also being removed, what am I missing?

Thanks!

It is removing SITE_MNT because the string exists in your long string with all the layer names.  What you need to do is create a list from your list of layer names.

Since you use nested quoted strings, you will need to be careful with your in comparison with the list.
