I agree with what was said above (it’s always better to avoid loops in Dynamo).  
However, I may have something that may help you (if loops is truly what you want). You could try something as described in the topic, you would “just” have to create a custom node that contains all your existing script. Hope this helps 🙂

> Hi everyone. Let’s say I have the script to create the circle which has 10\*t diameter (t is the sequence from 1 to 100). Is there any loop condition node to make dynamo create totally 100 circles with different diameter value (because there are 100 values of parameter t). Thank you.
