The arcgis.rand() function was primarily used to support creation of random values with the Calculate Value and Calculate Field tools, the Random Number Generator environment setting, and the CreateRandomValueGenerator function. Comparable functions using Python's random module should be used instead....
r = randomUniform (nRandom) for i in range(0, nRandom): r[i] = r[i]*(b-a) + a; Example In this example, randomUniform generates five pseudorandom uniform numbers. Since function randomOption is not called, the generator used is a simple multiplicative congruential one with a multipli...
