Retrieving features from a feature class with SearchCursor

There are many occasions when you need to retrieve rows from a table or feature class for read-only purposes. For example, you might want to generate a list of all land parcels in a city with a value greater than $100,000. In this case, you don't have any need to edit the data. Your needs are met simply by generating a list of rows that meet some sort of criteria. A SearchCursor object contains a read-only copy of rows from a table or feature class. These objects can also be filtered through the use of a where clause so that only a subset of the dataset is returned.

Getting ready

The SearchCursor() function is used to return a SearchCursor object. This object can only be used to iterate a set of rows returned for read-only purposes. No insertions, deletions, or updates can occur through this object. An optional where clause can be set to limit the rows returned. In this recipe, you will learn how to create a basic SearchCursor object...
