I posted that code piece of code for explanation purposes only, loop iteration i.e. the stop value is not fixed and will vary each time depending on user input (it is taken from the user at run time using vars_prompt)
Please can you tell me how to do x=x+y with x=10(will change with each loop iteration) and y=5 (remains constant), inside a loop that runs ten any number of time On Friday, August 22, 2014 10:27:42 AM UTC-7, Henry Finucane wrote: > > On Thu, Aug 21, 2014 at 11:17 PM, Imran Khan <[email protected] > <javascript:>> wrote: > > Thank you for your quick reply: > > But this works, but not in a loop! > > > > - name: bashless math > > set_fact: > > IPOctet: "{{ (ServerIPRange|int/epcrange|int)+IPOctet|int }}" > > with_sequence: start=1 end=4 > > register: IPOctet > > You may have missed a crucial bit of what I wrote- your algorithm > doesn't actually require any iteration.
