At a minimum, you are missing a comma after the first argument in your SearchCursor. Try fixing that first.

TypeError: means that you are trying to perform an operation on a value whose type is not compatible with that operation. An Iterable is a collection of elements that can be accessed sequentially . In Python, iterable objects are indexed using numbers . When you try to access an iterable object using a string or a float as the index, an error will be returned as TypeError: string indices must be integers. This means that when you're accessing an iterable object like a string or float value, you must do it using an integer value.

I cant edit the first post.

Look for the edit button at upper right (you can't edit in a dropdown but you can edit by clicking up there).

Not that it matters that much: new Geonet platform soon!

You might check the value type which script returns, it looks like the type is string rather than integer.

ohhhhhhhhhhhh thats it i bet

Side by Side comparison of jupytr notebook and Pro

This is what I ran. I cant edit the first post. And I just learned that it helps to set the language before you past code

That was what was in the Python window in Pro.

Normally when I used cursors, row[0] is not an issue

and it works in this:

PLOCU_set<SPAN class="operator token">=</SPAN> set<SPAN class="punctuation token">(</SPAN>r<SPAN class="punctuation token">[</SPAN><SPAN class="number token">0</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">.</SPAN>replace<SPAN class="punctuation token">(</SPAN><SPAN class="string token">" "</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">""</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="keyword token">for</SPAN> r <SPAN class="keyword token">in</SPAN> arcpy<SPAN class="punctuation token">.</SPAN>da<SPAN class="punctuation token">.</SPAN>SearchCursor<SPAN class="punctuation token">(</SPAN>fc<SPAN class="punctuation token">,</SPAN> <SPAN class="punctuation token">[</SPAN><SPAN class="string token">"PLOCU_"</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="keyword token">if</SPAN> <SPAN class="operator token">not</SPAN> r<SPAN class="punctuation token">[</SPAN><SPAN class="number token">0</SPAN><SPAN class="punctuation token">]</SPAN> <SPAN class="keyword token">is</SPAN> None<SPAN class="punctuation token">)</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

I tried to make it look better from what was pasted in from Pro. The code runs fine in a jupytr notebook.

also, lines 4 and 5 are not indented properly

It looks like you posted a partial Traceback, can you share the whole thing? Does Line 1 in your code snippet line up with Line 1 in the error message? I am guessing not because setting a variable to zero would not generate a TypeError.
