[GitHub] [spark] zhengruifeng opened a new pull request, #42680: [SPARK-44965][PYTHON] Hide internal functions/variables from `pyspark.sql.functions`
zhengruifeng opened a new pull request, #42680:
URL: https://github.com/apache/spark/pull/42680
### What changes were proposed in this pull request?
Hide internal functions/variables from `pyspark.sql.functions`
### Why are the changes needed?
internal functions/variables should not be exposed to end users:
```
Welcome to
____ __
/ __/__ ___ _____/ /__
_\ \/ _ \/ _ `/ __/ '_/
/__ / .__/\_,_/_/ /_/\_\ version 3.4.1
/_/
Using Python version 3.10.12 (main, Jul 5 2023 15:02:25)
Spark context Web UI available at http://localhost:4040/
Spark context available as 'sc' (master = local[*], app id = local-1692949938125).
SparkSession available as 'spark'.
In [1]: from pyspark.sql.functions import to_str
In [2]: ??to_str
Signature: to_str(value: Any) -> Optional[str]
Source:
def to_str(value: Any) -> Optional[str]:
"""
A wrapper over str(), but converts bool values to lower case strings.
If None is given, just returns None, instead of converting it to string "None".
"""
if isinstance(value, bool):
return str(value).lower()
elif value is None:
return value
else:
return str(value)
File: ~/.dev/bin/spark-3.4.1-bin-hadoop3/python/pyspark/sql/utils.py
Type: function
```
`to_str` here is a internal helper function
### Does this PR introduce _any_ user-facing change?
yes
