python实现批量dat转excel.py

import os,time,xlwt
def single(filepath):
'''参数：txt文件路径，功能将其转换成excel文件'''
print(filepath)
data = []
newname= filepath.replace(".txt",".xls")
print("+++++++++++++++++++++++++++++")
print(newname)
fp = open(filepath,"r",encoding="utf-8")
for line in fp: #设置文件对象并读取每一行文件
# print(type(line)) # str
line = line.split('|@|')
data.append(line)
row_num = len(data)
col_num = len(data[0]) #如果是空文件此处报错
# 步骤2：创建工作簿对象workbook
workbook = xlwt.Workbook(encoding='utf-8')
# 步骤3：创建单页对象sheet
sheet = workbook.add_sheet('测试单页1')
# 步骤5：写入内容数据
# 步骤5-1：外层for循环控制行数
for rowIndex in range(0, row_num):
# 步骤5-2：内层for循环控制列数
for colIndex in range(col_num):
# 步骤5-3：写入内容数据
sheet.write(rowIndex, colIndex, data[rowIndex][colIndex])
# 步骤6：保存工作簿
workbook.save(newname)
