+Subject: [PATCH] Use type checks in `generators/lattice.py` for Py3.14 compat
+
+Replace the `TypeError` catching in `networkx/generators/lattice.py`
+with explicit type checks to make the code more reliable and fix it for
+Python 3.14.  Catching the exception immediately does not work
+in the second instance, because the code is constructing a generator,
+and apparently Python 3.14 does not evaluate the `p in periodic`
+expression until the generator is actually iterated over.  Given that
+the function expects either an iterable or a `bool`, explicitly checking
+for `bool` should both be more readable and more reliable.
+
+The alternative would be to replace the generator with a list
+comprehension that would be evaluated immediately.  However,
+the explicit type check seems to be a cleaner solution to the problem.

+  NetworkX is a Python-based package for the creation, manipulation, and
+  study of the structure, dynamics, and functions of complex networks.
+  The structure of a graph or network is encoded in the edges (connections,
+  links, ties, arcs, bonds) between nodes (vertices, sites, actors). If
+  unqualified, by graph we mean a simple undirected graph, i.e. no
+  self-loops and no multiple edges are allowed. By a network we usually
+  mean a graph with weights (fields, properties) on nodes and/or edges.
+  The potential audience for NetworkX includes: mathematicians, physicists,
+  biologists, computer scientists, social scientists.
