There is too much duplication on the previous page, and what if we want to add more animals? Let's use a 'for loop':

# animals.tf.py

from pretf.api import block


def pretf_blocks():
    animals = ["dog", "cat", "buffalo", "rabbit", "badger"]
    for name in animals:  # loop over list
        yield block("resource", "random_integer", name, {  # dynamic resource name
            "min": 1,
            "max": 10,
        })

Now run pretf plan and you will see those 5 resources.

Why not use 'count'?

Terraform supports creating resources from a list like this:

resource "random_integer" "animals" {
  count = length(var.animals)
  min   = 1
  max   = 10
}

But at the time of this writing, Terraform 0.12.4 is the latest version, and it still recreates resources when you change the list.
