有没有办法使用xlrd关闭工作簿

Question

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?

Answer 1

深入到邮件列表存档 ，似乎文件对象由构造函数直接关闭，因此您无需显式关闭它。

Answer 2

open_workbook在返回之前调用release_resources（关闭mmaped文件）。
