 <p>Did you notice what was missing? Tuples <i class=baa>&amp;</i> bytes! <abbr>JSON</abbr> has an array type, which the <code>json</code> module maps to a Python list, but it does not have a separate type for &#8220;frozen arrays&#8221; (tuples). And while <abbr>JSON</abbr> supports strings quite nicely, it has no support for <code>bytes</code> objects or byte arrays.
