milenkovicm opened a new pull request, #1271:
URL: https://github.com/apache/datafusion-python/pull/1271
# Which issue does this PR close?
Closes #.
# Rationale for this change
Expose DataFrame.select_exprs method, which is supported in DataFusion, this
method is similar to
[pyspark.select_expr](https://spark.apache.org/docs/latest/api/python/reference/pyspark.sql/api/pyspark.sql.DataFrame.selectExpr.html)
Method will parse string expressions into logical plan expressions, making
easier to create select statements when expressions are involved
```python
df_3 = df.select_exprs(
"abs(a + b)",
"abs(a - b)",
)
```
It would be ideal if we could support expressions on df.select(...) but that
change looked as a bit complicated for me.
