<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.
