Accessing a dictionary item using a variable

[Spiro Mitsialis]

I would like to access data in a dictionary by referencing a variable.  I have the following dict:

"vlan_list": {
   "1": {
     "id": "1",
     "name": "Management",
     "status": "active"
   },
   "2": {
     "id": "2",
     "name": "VLAN 2",
     "status": "active"
   },
   "3": {
     "id": "3",
     "name": "VLAN 3",
     "status": "active"
   }
}

I also have a variable:

vlan: 2

I'd like to do:
- debug:
     var: vlan_list[vlan]

This does not work?  How can I user the variable "vlan" to get what is the info for VLAN 2 in the dict vlan_list?

Thanks

Your `vlan_list` is keyed with strings, not integers.  So you would either need to set `vlan: "2"` so that `vlan` is a string, or use `vlan_list[vlan|string]` in your debug.

Thanks Matt,

That worked.  I also found the following works (by trial and error)

vlan_list["{{ vlan }}"]
