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 = line[0:indexA]

questionStr.lstrip()

indexB = line.find('B')

answerA = line[indexA:indexB]

indexC = line.find('C')

indexE = line.find('(')

answerB = ''

if indexC>0:

answerB = line[indexB:indexC]

else:

answerB = line[indexB:indexE]

indexD = line.find('D')

answerC = ''

answerD = ''

if indexD>0:

answerC = line[indexC:indexD]

answerD = line[indexD:indexE]

else:

answerC = line[indexC:indexE]

answer = line[line.find('('):line.find(')')]

cindex = 0

questionStrCopy = ''

for c in questionStr:

if cindex<3:

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

questionStrCopy = questionStr[cindex+1:]

cindex = cindex + 1

answerA = answerA[1:]

answerB = answerB[1:]

answerC = answerC[1:]

answerD = answerD[1:]

answer = answer.strip('(')

print answer

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

questionStrCopy = questionStrCopy.lstrip()

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

continue

sheet.write(i, 0 , questionStrCopy)

sheet.write(i, 1 , answerA)

sheet.write(i, 2 , answerB)

sheet.write(i, 3 , answerC)

sheet.write(i, 4 , answerD)

sheet.write(i, 5 , answer)

i = i + 1

file.save(excelFileName)
