Python实现读取txt文件并转换为excel的方法示例

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)
