Create random numbers in python

[eriikforsberg]

Hi everyone!

I’m quite new to python and especially python for dyanmo. What I’m doing requires me to create random numbers inside a python code block but I can’t get it to work. I understand that I probably need to import a library to do this, but I don’t really understand how it works or how I should do it. What I’ve tried so far is to import the .NET reference, but I would like to reference a python library that does this. Any suggestions on how this can be done?

Thanks!

I think this post would guide you to random numbers.

Exception in random numbering node

So this code block takes four inputs - a minimum value, a maximum value, a minimum void, and a maximum void. It then crates a random list just like the Math.Random node. It then finds the midpoint of the void (half way between the minimum void and the maximum void). It then tests if any of the resulting numbers are between the minimum void and the midpoint of the void, and generates a new random number between the minimum value and the minimum void, and replaces the initial input with that. Num…

Hi @eriikforsberg,

You have a native Random module in Ironpython :

You need to add the sys.path to import the module.
For example :

import sys
sys.path.append("C:\Program Files (x86)\IronPython 2.7\Lib")
import random
OUT = random.random()

You also have a System Random in .Net:
For example :

import clr
import System.Random
OUT = System.Random(2).Next(1,10)

Thank you so much, works like a charm!

Thank you @SeanP! I’ve looked at this and this code is super useful! I actually even created a component from it so I have it saved!
