文件处理函数

del_sn_temp 递归删除一个文件夹下的所有文件



rereaddata 相当于读取一个文件 给它加上逗号 ( 制作模板时用到,c文件中的模板需要用逗号隔开，如果给的文件以空格隔开，需要加上逗号)





read_sample_all 读取一个文件夹下的模板(都是一个字符的模板) 取其0.1~0.9范围的平均



然后写入字母模板文件 需要自己略微调整一下-Del_sn_temp recursively delete all files in a folder

Rereaddata is equivalent to read a file to it with a comma (when making a template, the template in the C file need to be separated by commas, if the file to be separated by space, need to add a comma)

Read_sample_all read a folder under the template (both a character template) to take the average of its 0.1~0.9 range

And then write the letter template files need to adjust their own slightly
