I think this is closest to mutable C struct type.</p> <p>Same as collections.namedtuple but subclasses list, so fields may be modified. Same as popular Record class but smaller and faster. <a href="http://code.activestate.com/recipes/502237-simple-record-aka-struct-type/" rel="nofollow">http://code.activestate.com/recipes/502237-simple-record-aka-struct-type/</a></p>

<p style="color: grey"> Python recipe 577895 by <a href="/recipes/users/4177816/">Eric Snow</a> (<a href="/recipes/tags/freeze/">freeze</a>, <a href="/recipes/tags/immutable/">immutable</a>, <a href="/recipes/tags/mutable/">mutable</a>, <a href="/recipes/tags/unfreeze/">unfreeze</a>). </p> <p>Python already provides immutable versions of many of the mutable built-in types. Dict is the notable exception. Regardless, here is a protocol that objects may implement that facilitates turning immutable object mutable and vice-versa.</p>
