本文实例讲述了Python实现读取txt文件并转换为excel的方法。分享给大家供大家参考，具体如下：
这里的txt文件内容格式为：
892天平天国定都在？A开封B南京C北京（B）
Python代码如下：
# coding=utf-8
'''''
main function：主要实现把txt中的每行数据写入到excel中
'''
#################
#第一次执行的代码
import xlwt #写入文件
import xlrd #打开excel文件
import os
txtFileName = 'questions.txt'
excelFileName = 'questions.xls'
if os.path.exists(excelFileName):
os.remove(excelFileName)
fopen = open(txtFileName, 'r')
lines = fopen.readlines()
#新建一个excel文件
file = xlwt.Workbook(encoding='utf-8',style_compression=0)
#新建一个sheet
sheet = file.add_sheet('data')
############################
#写入写入a.txt，a.txt文件有20000行文件
i=0
j=0
for line in lines:
indexA = line.find('A')

questionStr.lstrip()

answerC = line[indexC:indexD]

else:

if c>='0' and c<='9':

print answer
print questionStrCopy, answerA, answerB, answerC, answerD, answer

if questionStrCopy=='' or answerA=='' or answer=='':
continue
