title: How to remove or exclude an item in an Ansible template list?
body: <p>I'm writing an Ansible template that needs to produce a list of ip's in a host group, <strong><em>excluding</em></strong> the current hosts IP. I've searched around online and through the documentation but I could not find any filters that allow you to remove an item in a list. I have created the (hacky) for loop below to do this but was wondering if anyone knew a "best practice" way of filtering like this.</p>
  
  <pre><code>{% set filtered_list = [] %}
  
  {% for host in groups['my_group'] if host != ansible_host %}
      {{ filtered_list.append(host)}}
  {% endfor %}
  </code></pre>
  
  <p>Lets say groups['my_group'] has 3 ip's (192.168.1.1, 192.168.1.2 and 192.168.1.3). When the template is generated for 192.168.1.1 it should only print the ip's 192.168.1.2 and 192.168.1.3.</p>
