Join Jeremy Graham for an in-depth discussion in this video Nested loops, part of Dynamo for Revit: Python Scripting.
- [Instructor] Now we have a good understanding…of how loops work,…let's take a look at nesting the for loop.…This is basically putting one or more loops…inside of another loop, which becomes useful…when working with nested lists.…As you can see, I've got the Dynamo exercise file…open for this chapter.…Currently, there are a series of rectangles being created…and exploited with the Geometry Exploit node,…which we'll use shortly.…Before we do, let's understand how nested loops work…by creating our own nested list.…Go ahead and place a new Python Script node.…
Let's start by creating a range of numbers…using the range method and we'll assign them…to the list variable, say 10 numbers.…And then let's create an empty list, say output,…and we'll use this to append items to in our for loop.…So next, let's create a for loop…like we have in previous videos with a variable named x…and the range of numbers we've just created.…Within this loop, let's create a point…using this x variable as the x coordinate,…and we'll assign this to the variable p.…
