<p><code>json.load()</code> doesn&#8217;t know anything about any conversion function you may have passed to <code>json.dump()</code>. What you need is the opposite of the <code>to_json()</code> function&nbsp;&mdash;&nbsp;a function that will take a custom-converted <abbr>JSON</abbr> object and convert it back to the original Python datatype.
<pre class=pp><code>
<a>def from_json(json_object): <span class=u>&#x2460;</span>
<a> if '__class__' in json_object: <span class=u>&#x2461;</span>
# add this to customserializer.py
<a>def from_json(json_object): <span class=u>&#x2460;</span></a>
<a> if '__class__' in json_object: <span class=u>&#x2461;</span></a>

<a> return time.strptime(json_object['__value__']) <span class=u>&#x2462;</span></a>

<li>This conversion function also takes one parameter and returns one value. But the parameter it takes is not a string, it&#8217;s a Python object&nbsp;&mdash;&nbsp;the result of deserializing a <abbr>JSON</abbr>-encoded string into Python.
