adamreeve opened a new issue, #43145:
URL: https://github.com/apache/arrow/issues/43145

   ### Describe the bug, including details regarding any error messages, 
version, and platform.
   
   Reproduced using PyArrow 16.1.0 on Fedora 39 Linux. The null values are 
still displayed as null when printing, but if round tripped via Parquet they 
are lost:
   
   ```python
   import pyarrow as pa
   import pyarrow.parquet as pq
   
   schema = pa.schema([
       pa.field("x", pa.int64(), nullable=False)])
   
   table = pa.Table.from_pydict({
           "x": [1, None, 3],
       }, schema=schema)
   
   print(f"Original table:\n{table}\n")
   
   pq.write_table(table, 'data.parquet')
   read = pq.read_table('data.parquet')
   
   print(f"Table from Parquet:\n{read}")
   ```
   
   This outputs:
   ```
   Original table:
   pyarrow.Table
   x: int64 not null
   ----
   x: [[1,null,3]]
   
   Table from Parquet:
   pyarrow.Table
   x: int64 not null
   ----
   x: [[1,0,3]]
   ``` 
   
   Is this expected behaviour? I would have thought this should raise an 
exception when the table is created.
   
   ### Component(s)
   
   Python
