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.
