 import xlrd　　#xlrd is a library for reading data and formatting information from Excel files, whether they are .xls or .xlsx files.



 data = xlrd.open_workbook('通讯录.xlsx')#打开 Excel文件

 print(type(data))

 table = data.sheets()[0]

 print(type(table))

 nrows = table.nrows #行数

 print("行数:{}".format(nrows))

 ncols = table.ncols #列数

 print("列数:{}".format(ncols))

 for i in range(0,nrows):

     rowValues = table.row_values(i) #某一行数据

     #print(type(rowValues))

     #print(rowValues)

     print("姓名:{}<-->电话:{}".format(rowValues[0], rowValues[1]))

xlrd.open_workbook(filename=None, logfile=<_io.TextIOWrapper name='<stdout>' mode='w' encoding='UTF-8'>, verbosity=0, use_mmap=1, file_contents=None, encoding_override=None, formatting_info=False, on_demand=False, ragged_rows=False)

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(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.该函数返回一个list，默认包含这一行的cells的所有内容。
