说明

接着推进计划，先不讲形式，先实验起来

内容

有一个文件夹，里面有很多7z压缩包(文件夹名称是日期)，希望以后放进新的压缩包时可以半自动的解压

1 这个任务很低频，所以其实也容易忘记
2 文件很多，我不想一一指定文件名
3 不想有额外的环境搭建，直接run一下就好

在文件夹里建立一个程序runtime.py,内容如下：

'''
docker run -it\
 -v /etc/localtime:/etc/localtime  \
 -v /home/jupyter_data:/workspace \
 -v /etc/timezone:/etc/timezone\
 -v /home/bigdisk:/home\
 -e "LANG=C.UTF-8"\
 YOUR_IMAGE\
 bash

'''

    for the_file in tier2_files:
        the_file_tag = Path(fpath + the_file)
        if the_file_tag.is_dir():
            if special_char in the_file:
                res_list.append(fpath + the_file + '/')
    if verbose:
        print('find %s folders' %  len(res_list))
    return res_list


def get_batch_file1(fpath, suffix, fetch_num, is_sorted =True):
    flist = [x for x in os.listdir(fpath) if x.endswith(suffix)]
    if is_sorted:
        flist.sort()
    return flist[:fetch_num]
