打開一個Excel文件。
這裏先簡單的介紹基本的參數,以後有用到再添加。
Parameters:
filename – The path to the spreadsheet file to be opened.
指定要打開文件的路徑
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,並保存在list中。
All sheets not already loaded will be loaded.
classxlrd.sheet.
Sheet
(book, position, name, number)
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
(rowx, start_colx=0, end_colx=None)
Returns a slice of the values of the cells in the given row.該函數返回一個list,默認包含這一行的cells的所有內容。
