## Summary
This PR changes how we format `with` statements with a single with item
for Python 3.8 or older. This change is not compatible with Black.
This is how we format a single-item with statement today
```python
def run(data_path, model_uri):
with pyspark.sql.SparkSession.builder.config(
key="spark.python.worker.reuse", value=True
).config(key="spark.ui.enabled", value=False).master(
"local-cluster[2, 1, 1024]"
).getOrCreate():
# ignore spark log output
spark.sparkContext.setLogLevel("OFF")
print(score_model(spark, data_path, model_uri))
```
This is different than how we would format the same expression if it is
inside any other clause header (`while`, `if`, ...):
```python
def run(data_path, model_uri):
while (
pyspark.sql.SparkSession.builder.config(
key="spark.python.worker.reuse", value=True
)
.config(key="spark.ui.enabled", value=False)
.master("local-cluster[2, 1, 1024]")
.getOrCreate()
):
# ignore spark log output
spark.sparkContext.setLogLevel("OFF")
print(score_model(spark, data_path, model_uri))
```
Which seems inconsistent to me.
This PR changes the formatting of the single-item with Python 3.8 or
older to match that of other clause headers.
```python
def run(data_path, model_uri):
with (
pyspark.sql.SparkSession.builder.config(
key="spark.python.worker.reuse", value=True
)
.config(key="spark.ui.enabled", value=False)
.master("local-cluster[2, 1, 1024]")
.getOrCreate()
):
# ignore spark log output
spark.sparkContext.setLogLevel("OFF")
print(score_model(spark, data_path, model_uri))
```
According to our versioning policy, this style change is gated behind a
preview flag.
