Focusing on the issue here: I was leaning to going with the suggestion from above to just default to string dtype columns. However, that also introduces a special case (default Index object in a Series/DataFrame if not specified is always a RangeIndex, except for the len-0 case if it is...
A table with multiple columns is aDataFrame. A column of a DataFrame, or a list-like object, is aSeries. ADataFrameis a table much like in SQL or Excel. It's similar in structure, too, making it possible to use similar operations such as aggregation, filtering, and pivoting. However,...
