How to loop or iterate in terraform?

Workspace

How to pass diff values to diff env using diff workspace?

Step 1 - Create terrafrom.tfvars [ Default Workspace ]

tagsvalue = "this-is-default"
numofecc2 = 20
cpu = 2
dbcpu = 6
appcpu =4
azs = ["10.0.1.0/24", "10.0.2.0/24", "10.0.3.0/24"]

Step 2 - Create qa.tfvars

tagsvalue = "this-is-qa"
numofecc2 = 5
dbcpu = 4
appcpu = 2
azs = ["10.0.1.0/24", "10.0.2.0/24", "10.0.3.0/24"]

Step 3 - Go to default workspace
$ terraform workspace select default
$ terraform apply --auto-approve [ Loading - terrafrom.tfvars and This would store state file in terraform.tfstate ] 

Step 4 - Go to qa workspace
$ terraform workspace select qa
$ terraform apply --auto-approve -var-file="qa.tfvars" [ This would store state file in terraform.tfstate.d/qa.terraform.tfstate ]
