For that you need one only call to Seed at init().

I wouldn't recommend using rand.Seed as you do: this defeats any attempt at
getting reproductible results.

[go-nuts] Re: Random Number Generation in a given range

Alok,

Your import path "github.com/alok87/goutils/random" is not valid for "go 
get". The source is at "github.com/alok87/goutils/pkg/random".

You write "for { rand.Seed(); rand.Intn(); }". Therefore, the range of 
values is not random.

You write "arr[r] = rand.Intn(max) + min" which is incorrect.

And so on.

Peter

A python like range utility which can be used for this
