办公自动化26-将大的txt文件切割为多个小的txt文件

本次代码借鉴网上高手，放在这里以备个人之需

#读入用于切割的原始大文件
open_diff = open(r'G:\LOST.DIR\all.txt', 'r',encoding = 'UTF-8')
diff_line = open_diff.readlines()

line_list = []
for line in diff_line:
    line_list.append(line)
#切分diff,2000的意思是每个单个小文件保存2000lines
diff_match_split = [line_list[i:i+2000] for i in range(0,len(line_list),2000)]

#将切分的写入多个txt中\n",
for i,j in zip(range(0,len(diff_match_split)),range(0,len(diff_match_split))):
    with open('newdiff_match%d.txt'% j,'w+') as temp:
#with open('newdiff_match%d.txt'% j,'w+'，encoding = "utf-8") as temp:通过encoding可以自定义想要的编码格式，不设置encoding,默认保存为GBK即ANSI的格式
        for line in diff_match_split [i]:
            temp.write(line)

加油鸭！^_^
