Python Scan 文件夹和子文件夹。子文件夹。只处理指定文件

Question

我正在做 PDF Flatting 但挑战是源 pdf 存储“c:\root folder\folder1\subfolders1\subfolders” 每个文件夹和子文件夹都有 PDF，并且在 pdf 平面化完成后文件保存在不同的位置，但结构仍然存在与 c:\folder1\subfolders1\subfolders 相同。 文件夹结构示例 enter image description here

我面临挑战，因为 PDF 名称是这样的（06032021_toibhoc_mp_01_1_col_r1.pdf、06032021_toibhoc_PP_01_1_col_r1.pdf、06032021_toiind_mp_01_1_col_r1.pdf）

文件名语法：- Date_Techcode_mp_pageno_edition_number_col_page_revisionnumber

我只需要关注日期和技术代码（即 06032021_toibhoc），因为这在每个文件中都是唯一的。 情况1： 如果文件名以明天日期开头，我想检查日期，而今天日期只处理它们。 案例2。 我想通过 JSON 文件检查技术代码。我有一个我想增肥的商店技术代码，因此如果 JSON 文件技术代码仅存在于该文件进程中的文件名中，则程序应将文件名教学代码与 JSON 文件进行比较，否则它会在没有进程的情况下复制到目标。

json 文件示例。 {"toiac_mp","toiac_pp","su_mp","rjk_mp","rjk_pp","bar_mp","cap_mp",”cap_pp”"}

案例3：- 我的工作时间是下午 3 点到凌晨 2 点，因为我希望它在设定的工作时间之后改变

我尝试使用以下代码来处理文件夹中和子文件夹中的每个文件。

用于处理（06032021_toibhoc_mp_01_1_col_r1.pdf、06032021_toibhoc_PP_01_1_col_r1.pdf、06032021_toiind_mp_01_1_col_r1.pdf）

首先可以读取配置文件

def read_config():
    with open('/path/filename.config', 'r') as lookupfile:#use your path name 
        for line in lookupfile:
            tech= [word[1:-1] for word in line.split(",")]
            return tech

然后您可以使用 DateTime 获取日期并使用 fnmatch.fnmatch 搜索文件。检查今天和明天的文件，你可以同时使用

tom_date=(datetime.today()+timedelta(days=1)).strftime("%d%m%Y")
today_date=(datetime.now()).strftime("%d%m%Y")
patterns=(tom_date+'_'+techcode+'*',today_date+'_'+techcode+'*')
if [pat for pat in patterns if fnmatch.fnmatch(file,pat)]:
       #do waht you want
