Accessing a dictionary item using a variable

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 }}”]
