>                 URL: https://issues.apache.org/jira/browse/SPARK-40922
>             Project: Spark
>          Issue Type: Documentation
>          Components: Pandas API on Spark, PySpark
>    Affects Versions: 3.3.1
>            Reporter: Stefaan Lippens
>            Priority: Minor
>
> The {{path}} argument of {{pyspark.pandas.read_csv(path, ...)}} currently has type annotation {{str}} and is documented as
> {code}
>     path : str
>         The path string storing the CSV file to be read.
> {code}
> The implementation however uses {{pyspark.sql.DataFrameReader.csv(path, ...)}} which does support multiple paths:
> {code}
>         path : str or list
>             string, or list of strings, for input path(s),
>             or RDD of Strings storing CSV rows.
> {code}
> Loading multiple CSV files at once is a useful feature to have and should be documented (and tested for)
