python–xlwt库的使用
学习目标
- 复习python基本语法
- 在Linux系统下，掌握从txt文件中提取数据到exel文件的方法
- 将HM16.9生成的
学习方法：举一反三&触类旁通

import xlwt
import os
要点概括
import xlwt
- Python语言中，写入Excel文件的扩展工具。
- 相应的有xlrd扩展包，专门用于excel读取。
- 可以实现指定表单、指定单元格的写入。
- 支持excel03版到excel2013版，保存的格式只支持xls格式，07以后的版本xlsx不支持。
- 使用时请确保已经安装python环境。
- 在python中写excel表要用到xlwt [1] 模块，大致使用流程如下：
- 导入模块
import xlwt - 创建workbook（其实就是excel，后来保存一下就行）
workbook = xlwt.Workbook(encoding = ‘ascii’) - 创建表
worksheet = workbook.add_sheet(‘My Worksheet’) - 往单元格内写入内容
worksheet.write(0, 0, label = ‘Row 0, Column 0 Value’) - 保存
workbook.save(‘Excel_Workbook.xls’)
- 以上是最基本的功能。
import os
os.path模块主要用于文件的属性获取，在编程中经常用到，以下是该模块的几种常用方法。更多的方法可以去查看官方文档：http://docs.python.org/library/os.path.html
为什么要学xlwt？
- python操作excel主要用到xlrd和xlwt这两个库，即xlrd是读excel，xlwt是写excel的库。

上机实践
安装
ubuntu系统下安装xlwt库：
(base) yupengfei@yupengfei-X550VX:~$ pip install xlwt
Requirement already satisfied: xlwt in ./anaconda3/lib/python3.7/site-packages (1.3.0)
(base) yupengfei@yupengfei-X550VX:~
电脑上已经安装了这个库
写脚本
#一次性把所有配置的序列数据结果提取出来
## extract_txt_xls_ypf.py
#格式要求：**_QP32_AI.txt
import os
import xlwt
#所有序列数据主名称
path='../CTC_txt/22'
def load_file_list(directory):
list = []
for filename in [y for y in os.listdir(directory) if os.path.isfile(os.path.join(directory,y))]:
if filename.split('.')[-1]=='txt':
list.append(filename.split('.txt')[0])
return sorted(list)
name=load_file_list(path)
print(name)
path='../CTC_txt/'
#创建表，第一次循环（编码模式）,第二次循环（qp）
f = xlwt.Workbook()
for mode in ['AI']:
sheet = f.add_sheet(mode, cell_overwrite_ok=True)
j = 1
i = 0
for name_seq in name:
print(name_seq)
sheet.write(j, 1, name_seq)
for i in range(0,4):
sheet.write(j+i, 2, 22+5*i)
with open(path+'/'+str(22+5*i)+'/'+name_seq+'.txt') as ftxt:
content = ftxt.read().splitlines()
data1=content[-16].split( )
print(data1)
data2=content[-1].split( )
data = data1[2:]
k=3
for target in data:
sheet.write(j+i,k,target)
k=k+1
j+=4
f.save('CTC169_count.xls')
运行结果
