打开一个Excel文件。

这里先简单的介绍基本的参数,以后有用到再添加。

Parameters:

  filename – The path to the spreadsheet file to be opened.

    指定要打开文件的路径

  logfile – An open file to which messages and diagnostics are written  

Returns:

  An instance of the Book class.

 

book.sheets()

Return:  A list of all sheets in the book. 返回Excel中所有的表,并保存在list中。

  All sheets not already loaded will be loaded.

 

classxlrd.sheet.Sheet(bookpositionnamenumber)

 

Contains the data for one worksheet.

In the cell access functions, rowx is a row index, counting from zero, and colx is a column index, counting from zero. Negative values for row/column indexes and slice positions are supported in the expected fashion.

Note: You don’t instantiate this class yourself. You access Sheet objects via the Book object that was returned when you called xlrd.open_workbook().

nrows= 0

  Number of rows in sheet. A row index is in range(thesheet.nrows).

ncols= 0

  Nominal number of columns in sheet. It is one more than the maximum column index found, ignoring trailing empty cells. See also the ragged_rows parameter to open_workbook() and row_len().

row_values(rowxstart_colx=0end_colx=None)

  Returns a slice of the values of the cells in the given row.该函数返回一个list,默认包含这一行的cells的所有内容。
