Ansible nested loops - loops

Question

I have a variable that looks like this:
device:
- sdb: 2
- sdc: 3
- sdd: 4
How can I produce the result with ansible loops:
sdb 1
sdb 2
sdc 1
sdc 2
sdc 3
sdd 1
sdd 2
sdd 3
sdd 4
I tried with_sequence and loop_control but it didn't work.

Answer 1

Wrote a debug task with ansible loop and jinja which should give you the desired result. Refactor as required.
- name: Debug device var
debug:
msg: "{% for key, value in item.iteritems() %}{% for i in range(value) %} {{ key }} {{ loop.index }} {% endfor %}{% endfor %}"
loop: "{{ device }}"

Answer 2

Finally, I got the solution but I changed the format of the variable, however. The variable is changed to:
device:
sdb: 2
sdc: 3
sdd: 4
The result is:
ok: [ceph-host-2] => (item=1) => {
"msg": "sdd 1"
}
ok: [ceph-host-2] => (item=2) => {
"msg": "sdd 2"
}
ok: [ceph-host-2] => (item=3) => {
"msg": "sdd 3"
}
ok: [ceph-host-2] => (item=4) => {
"msg": "sdd 4"
}
TASK [osd : debug]
ok: [ceph-host-2] => (item=1) => {
"msg": "sdb 1"
}
ok: [ceph-host-2] => (item=2) => {
"msg": "sdb 2"
}
TASK [osd : debug]
ok: [ceph-host-2] => (item=1) => {
"msg": "sdc 1"
}
ok: [ceph-host-2] => (item=2) => {
"msg": "sdc 2"
}
ok: [ceph-host-2] => (item=3) => {
"msg": "sdc 3"
}
main.yml
- include_tasks: inner.yml
loop: "{{ device.keys() }}"
loop_control:
loop_var: outer_item
inner.yml
- debug:
msg: "{{ outer_item }} {{ item }}"
with_sequence: count={{ device[outer_item] }}

Answer 3

The variable is:
device:
- sdb: 2
- sdc: 3
- sdd: 4
main.yml
- include_tasks: inner.yml
loop: "{{ device }}"
loop_control:
loop_var: outer_item
inner.yml
- debug:
msg: "{{ outer_item.keys()[0] }} {{ item }}"
with_sequence: count={{ outer_item.values()[0] }}
