I am trying to setup an variable when particular build length matches with the package version but it throws with the following error 

    - debug: var=builds[4] -> Getting value from the list works
    - set_fact: buildslen={{ builds | length }} -> Length of the list 
    - debug: var=pkgversion -> Package version
    - debug: var=buildslen 
    - debug: var=builds[{{item}}]
      with_sequence: start=0 count={{ buildslen }} -> Looping through all the versions works fine
    - set_fact: exactlen=builds[{{ item }}]
      when: builds[{{ item }}] == {{ pkgversion }} 
      with_sequence: start=0 count={{ buildslen }}
    - debug: var=exactlen

```

You dont need moustaches in conditionals:

when: builds[item] == pkgversion

Unfortunately its the same error

fatal: [[abc.xyz.com](http://abc.xyz.com)]: FAILED! =\> {“msg”: "The conditional check ‘builds[item] == pkgversion’ failed. The error was: error while evaluating conditional (builds[item] == pkgversion): ‘list object’ has no attribute u’0’
