使用Python操作excel文件

#coding=utf-8
import xlrd
'''
文件路径比较重要，要以这种方式去写文件路径不用
'''
file_path = r'd:/功率因数.xlsx'
#读取的文件路径
file_path = file_path.decode('utf-8')
#文件中的中文转码
data = xlrd.open_workbook(file_path)
#获取数据
table = data.sheet_by_name('历史数据')
#获取sheet
nrows = table.nrows
#获取总行数
ncols = table.ncols
#获取总列数

table.row_values(i)
#获取一行的数值
table.col_values(i)
#获取一列的数值

#获取一个单元格的数值
cell_value = table.cell(a,b).value
