If you pass a wildcard, in your case "pdf_template", it will still return a list with all the maps that match the wildcard (even if it is only one).In order to use the listLayers() method, you need to get the map first by indexing the list. I come to know about a function .clear() that clears the value inside a list. AttributeError: 'list' object has no attribute 'cost' this will occur when you try to call .cost on a list object. When I try to open an output file and write the record to the file, I receive the following error: AttributeError: 'str' object has no attribute 'write' Using list.append() in that case would add the list object to your list of words, which of course wouldn’t match any string input.
