使用python3+xlrd解析Excel的实例

# -*- coding: utf-8 -*-
import xlrd
def open_excel(file = 'file.xls'):#打开要解析的Excel文件
 try:
 data = xlrd.open_workbook(file)
 return data
 except Exception as e:
 print(e)

def excel_by_index(file = 'file.xls', colindex = 0, by_index = 0):#按表的索引读取
 data = open_excel(file)#打开excel文件
 tab = data.sheets()[by_index]#选择excel里面的Sheet
 nrows = tab.nrows#行数
 ncols = tab.ncols#列数
 colName = tab.row_values(colindex)#第0行的值
 list = []#创建一个空列表
 for x in range(0, nrows):
 row = tab.row_values(x)
 if row:
 app = {}#创建空字典
 for y in range(0, ncols):
 app [ colName[y] ] = row[y]
 list.append(app)
 return list

def read_excel(file = 'file.xls', by_index = 0):#直接读取excel表中的各个值
 data = open_excel(file)#打开excel文件

 print(tab.cell(x, y).value)
