CreateRandomValueGenerator example
Create and initialize random number generator object.
import arcpy
# CreateRandomValueGenerator takes 2 arguments, seed and distribution
# method. The distribution method options are ACM599,
# MERSENNE_TWISTER, and STANDARD_C.
#
# The gen variable is a randomNumberGenerator object that is assigned
# to the randomGenerator environments setting.
arcpy.env.randomGenerator = arcpy.CreateRandomValueGenerator(20, "STANDARD_C")
# Calculate a random number using the ArcGIS.Rand() function
result = arcpy.CalculateValue_management("arcgis.rand('normal 0.0 10.0')")
# Print the returned value from the Result object
print(float(result.getOutput(0)))
