Important thing about a list is that items in a list need not be of the same type. close, link 2. Recordsets are iterable so the usual Python tools are available for transformation (map (), sorted (), ifilter (),...) however these return either a list or an iterator, removing the ability to call methods on their result, or to use set operations. Certainly, it is used for more flexible operations. DataFrame from dict of array-like or dicts. Recordsets therefore provide these operations returning recordsets themselves (when possible): The only drawback of this method is that the elements of the set need to be sortable. in the result (any names not found in the data will become all-NA Figure 7 shows the corresponding ASP script that receives the recordset and sends the changes back to the database using the UpdateBatch method. In some coding languages, every item in the list must be the same data type. If the passed data do not have names associated with them, this argument provides names for the columns.
