# Handling boolean values

## lazy\_boolean filter

This utility can be used to easily compare a user-entered values (strings and numbers) and determine if its True or False. It contains logic for common user and dataset entered values.

### Examples

```markup
<div class="example">
  <p>Yes: {{ 'Yes'|lazy_boolean }}</p>
  <p>1: {{ 1|lazy_boolean }}</p>
	<p>No: {{ 'No'|lazy_boolean }}</p>
	<p>0: {{ 0|lazy_boolean }}</p>
</div>

{% set some_value = 'Yes' %}
{% if some_value|lazy_boolean %}
    <h2>Value is Yes - should show</h2>
{% endif %}

{% set some_value = 'No' %}
{% if some_value|lazy_boolean %}
    <h2>Value is No - should not show</h2>
{% endif %}
```

### True/False list

Below is a list of values that this supports.
