> Currently in PySpark (both Classic and Connect), if a user passes a length-1 list or tuple of {{StructType}} as the {{schema}} argument to {{{}createDataFrame{}}}, PySpark raises an unhelpful error message.
> Unfortunately it is easy for this to happen. For example if a user leaves a trailing comma at the end of the line that defines the {{{}StructType{}}}.
> Add some simple code to {{createDataFrame}} to handle this case more gracefully
