Lists allow you to group, sort, and filter through objects in Python as you would Dynamo. As the data structure that you will use most, learn all the fundamentals of lists and their functions available to you.
- [Instructor] While working in Dynamo,…you're probably more than experienced at using lists…to store numbers, geometry or Revit elements.…A list is used to store objects in an ordered manner.…In Dynamo, all data outputting from nodes…that is more than one item is essentially a list.…Let's have a look at some of the fundamentals…of using lists in Python.…As you can see, I've created a new Dynamo file,…so let's go ahead and place a new Python Script node.…Creating a list can be done in a few ways,…the simplest method is to use square brackets…to create an empty list.…
For example, let's create an empty list…by creating the variable name lst…and we'll assign to it two square brackets.…We now have an empty list…which we can check by outputting our variable.…We can also create a list with predefined items.…For example, let's create a list variable lstnums…and this time, we'll assign to it…the numbers zero through to four, separated by commas.…The commas are used to separate our objects…as separate items in the list.…
