Is there a way to close a workbook using xlrd

问题

I am using the function open_workbook() to open an excel file. But I cannot find any function to close the file later in the xlrd module. Is there a way to close the xls file using xlrd? Or is not required at all?

回答1:

Digging into the mailing list archive, it seems that the file object is closed directly by the constructor, so you don't need to close it explicitly.

回答2:

The open_workbook calls the release_resources ( which closes the mmaped file ) before returning.
