With arcpy, I want to calculate the mean value of a specific field in a shapefile and print the resulting value for the user. I use the Summary Statistics tool and it works, but the resulting value is stored in a table at a specific path, but how can I access the calculated value with python?

Here is my code. It will only output the path to the table, but I need the calculated value.

stats = arcpy.Statistics_analysis(myshapefile, "G:/temp/stats", [[field, "MEAN"]])

The way I would recommend to access the contents of a table is by using arcpy.da.SearchCursor() to read it:

SearchCursor establishes read-only access to the records returned from a feature class or table.

Returns an iterator of tuples. The order of values in the tuple matches the order of fields specified by the field_names argument

The asker also:

found a useful function on this website: https://arcpy.wordpress.com/2012/02/01/calculate-a-mean-value-from-a-field/

which groups the Summary Statistics with a Search Cursor to read its output and return the Mean value from a field.
