.csv格式文件转换为.dat文件

#!/user/bin/python
# -*- coding:utf8 -*-
import os
import re
import sys

file_name = 'movies'
xml_file_name = file_name + '.csv'
fobj = open(xml_file_name, 'r', encoding='gbk')  # 指定使用gbk编码读取CSV文件
fobj_dat = open(file_name + '.DAT', 'w', encoding='utf-8')  # 指定使用utf-8编码写入DAT文件
flag = True
testdata_num = 0
dic_task_des = {}
for line_num, line_content in enumerate(fobj.readlines()):
    if flag == True:
        testdata_num = testdata_num + 1
        line_content = re.sub(',\n|,\r\n|\n', '', line_content)
        line_content = re.sub(',', '::', line_content)
        fobj_dat.writelines(line_content + '\n')
fobj_dat.close()

task_des = {}
task_des[file_name] = dic_task_des

fobj.close()

file_name修改为自己的文件名字，如果原csv文件为utf-8格式，可修改为：fobj = open(xml_file_name, 'r', encoding='utf-8')
