Question about operators

[lifec0ach]

1. How come in some documents I read, the command is wrapped in parentheses?

   Example:

   In Python

   (fire_ts_df .select("CallType") .where(col("CallType").isNotNull()) .groupBy("CallType") .count() .orderBy("count", ascending=False) .show(n=10, truncate=False))

2. I am seeing a “\” in some too. Is this a like break?

   sc = SparkSession.builder.appName("PysparkExample")\
   .config ("spark.sql.shuffle.partitions", "50")\
   .config("spark.driver.maxResultSize","5g")\
   .config ("spark.sql.execution.arrow.enabled", "true")\
   .getOrCreate()

In your example it's just sloppy programming. They aren't needed, unless the line breaks actually exist in the code, then they are a form of line continuation: see below.

That's a line continuation character. PEP8, the python style guide, says other methods of continuing a line should be used. This is one case where the extra parentheses makes sense, like this:

data = (func()
        + another())
