用python来自动生成excel数据文件。python处理excel文件主要是第三方模块库xlrd、xlwt、xluntils和pyExcelerator，除此之外，python处理excel还可以用win32com和openpyxl模块。

方法一：

小罗问我怎么从excel中读取数据，然后我百了一番，做下记录

excel数据图(小罗说数据要给客户保密，我随手写了几行数据)：

python读取excel文件代码：

#!/usr/bin/env python
# -*- coding: utf-8 -*-
# 读取excel数据
# 小罗的需求，取第二行以下的数据，然后取每行前13列的数据
import xlrd
data = xlrd.open_workbook('test.xls') # 打开xls文件
table = data.sheets()[0] # 打开第一张表
nrows = table.nrows # 获取表的行数
for i in range(nrows): # 循环逐行打印
if i == 0: # 跳过第一行
continue
print table.row_values(i)[:13] # 取前十三列

excel的写操作等后面用到的时候在做记录

方法二：

使用xlrd读取文件，使用xlwt生成Excel文件（可以控制Excel中单元格的格式）。但是用xlrd读取excel是不能对其进行操作的；而xlwt生成excel文件是不能在已有的excel文件基础上进行修改的，如需要修改文件就要使用xluntils模块。pyExcelerator模块与xlwt类似，也可以用来生成excel文件。

1. [代码]test_xlrd.py

workbook = xlrd.open_workbook('E:\\Code\\Python\\testdata.xls')
#抓取所有sheet页的名称
worksheets = workbook.sheet_names()
print('worksheets is %s' %worksheets)
#定位到sheet1
worksheet1 = workbook.sheet_by_name(u'Sheet1')
"""
#通过索引顺序获取
worksheet1 = workbook.sheets()[0]

row = worksheet1.row_values(curr_row)

#遍历sheet1中所有列col
num_cols = worksheet1.ncols
for curr_col in range(num_cols):
col = worksheet1.col_values(curr_col)
print('col%s is %s' %(curr_col,col))
#遍历sheet1中所有单元格cell
for rown in range(num_rows):
for coln in range(num_cols):
cell = worksheet1.cell_value(rown,coln)
print cell
"""
#其他写法：
cell = worksheet1.cell(rown,coln).value
print cell
#或
cell = worksheet1.row(rown)[coln].value
print cell
#或
cell = worksheet1.col(coln)[rown].value
print cell
#获取单元格中值的类型，类型 0 empty,1 string, 2 number, 3 date, 4 boolean, 5 error
cell_type = worksheet1.cell_type(rown,coln)
print cell_type

#写入数据
ws.write(1, 1, 'changed!')
#添加sheet页
wb.add_sheet('sheetnnn2',cell_overwrite_ok=True)
#利用保存时同名覆盖达到修改excel文件的目的,注意未被修改的内容保持不变

#parse_xls返回一个列表，每项都是一个sheet页的数据。
#每项是一个二元组(表名,单元格数据)。其中单元格数据为一个字典，键值就是单元格的索引(i,j)。如果某个单元格无数据，那么就不存在这个值
