+# Python Metaclasses
+
+This folder provides the code examples for the Real Python tutorial [Python Metaclasses](https://realpython.com/python-metaclasses/).
+
+The tutorial demonstrates its examples in the interactive interpreter, so each
+REPL sequence is collected here as a runnable script that prints the output the
+tutorial shows. Run any of them with Python 3.14:
+
+```sh
+$ python custom_metaclass.py
+```
