stupids finally over parser:  Python Code block import numpy def rand_num(a_field):   return  numpy.random.randint(1,1000) the rest rand_num(!randnum!) where !randnum! is the field to place the random numbers.  I think you were mixing up the script example with the field calculator example and I just didn't catch it or better still provide a minimum and maximum value import numpy def rand_num(min_val, max_val):   return  numpy.random.randint(min_val,max_val) with rand_num(1,1000) calling the function ...

so it isn't returning a python list, however, looking at the help files and your example I noted 'INTEGER 1, 1000' was your case and in the help files at http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//001w0000000w000000.htm it was 'normal 0.0 10.0' the only difference between them, excluding the distribution type, was that you had a pesky "," after the 1 in yours and the help files seems to suggest that a space delimited string is used.  Barring that, try the help file example to rule out further issues. ...

you will have to reclassify the floating point slope values into integer classes (ie 5-10 deg slope = class 1 etc etc) so that you have the required integer grid to convert to polygons.  check the help files for more details. ... View more
