<p style="color: grey"> Python recipe 577434 by <a href="/recipes/users/178123/">Raymond Hettinger</a> (<a href="/recipes/tags/ast/">ast</a>, <a href="/recipes/tags/chained/">chained</a>, <a href="/recipes/tags/compiler/">compiler</a>, <a href="/recipes/tags/dictionary/">dictionary</a>, <a href="/recipes/tags/inheritance/">inheritance</a>, <a href="/recipes/tags/nested/">nested</a>, <a href="/recipes/tags/nonlocal/">nonlocal</a>, <a href="/recipes/tags/scopes/">scopes</a>, <a href="/recipes/tags/xml/">xml</a>). Revision 2. </p> <p>Easy to use chain of dictionaries for crafting nested scopes or for a tree of scopes. Useful for analyzing AST nodes, XML nodes or other structures with multiple scopes. Can emulate various chaining styles including static/lexical scoping, dynamic scoping and Python's own globals(), locals(), nested scopes, and writeable nonlocals. Can also model Python's inheritance chains: instance dictionary, class dictionary, and base classes.</p>

<p style="color: grey"> Python recipe 578046 by <a href="/recipes/users/2608421/">Stephen Chappell</a> (<a href="/recipes/tags/iteration/">iteration</a>, <a href="/recipes/tags/nested/">nested</a>). </p> <p>The "nest" generator function in this module is provided to make writing nested loops easier to accomplish. Instead of writing a for loop at each level, one may call "nest" with each sequence as an argument and receive items from the sequences correctly yielded back to the caller. A test is included at the bottom of this module to demonstrate how to use the code.</p>

Revision 2. </p> <p>This flattenizes any nested level list. I couln't find this in itertools module so I wrote it. Python 3 may be required.</p>
