+the workbook (e.g., invalid parameters, file I/O error, or even a Rust panic). 
+You can catch these exceptions in Python as follows:
+
+.. code-block:: python
+
+   from ironcalc import WorkbookError
+
+   try:
+       # Some operation on PyModel
+       pass
+   except WorkbookError as e:
+       print("Caught a workbook error:", e)
+
+``PyCellType``
+^^^^^^^^^^^^^^
+Represents the type of a cell (e.g., number, string, boolean, etc.). You can 
+check the type of a cell with :meth:`PyModel.get_cell_type`.
+
+``PyStyle``
+^^^^^^^^^^^
+Represents the style of a cell (font, bold, number formats, alignment, etc.). 
+You can get/set these styles with :meth:`PyModel.get_cell_style` 
+and :meth:`PyModel.set_cell_style`.
