在文本每行末尾加;

f = open(r'D:\test1\1.txt','rb')w = open(r'D:\test1\2.txt','wb')for line in f.readlines():         w.writelines(line.replace('\r\n',';\r\n'))w.close()

 更好的写法

f = open(r'D:\test1\1.txt','rb')w = open(r'D:\test1\2.txt','wb')import oswith f as lines:    with w as outfile:        for line in lines:            line = '"' + line.replace(os.linesep, "") + '",' + os.linesep            outfile.write(line)

 

 

类似写法

f = open(r'D:\test1\1.txt','rb') w = open(r'D:\test1\2.txt','wb') for line in f.readlines():          line = '"'+ line.replace('\r\n',"") + '";\r\n'          w.writelines(line) f.close() w.close()
