子目录中的python文件路径不正确

编辑：使用 Python 3.7 | 赢10

我已经阅读了很多关于在 python 中处理路径的帖子。尝试编写一个小脚本，按上次修改日期将所有文件和子目录文件分类到文件夹中。

到目前为止，它的工作原理是一个问题，当获取子目录时，它以 \ 开头返回，从而使最终目录字符串 base_dir/\subdir。

这意味着第一组文件被复制得很好，但子目录中的任何内容都失败了。

试图弄清楚如何阻止这种情况发生时感到头疼。希望在屏幕中断后我会弄清楚，但以防万一，如果这里有任何向导可以提供帮助，我们将不胜感激。

代码：

import os
import time
import datetime
import shutil
from typing import List, Tuple


SORT_DIR = r'to_sort/'


def date_from_seconds(file_stats):
    """
    Takes an os.stats variable and return a date
    Using the seconds elapsed since last modification
    """
    
    seconds = time.ctime(file_stats.st_mtime)
    date_filter = datetime.datetime.strptime(seconds, '%a %b %d %H:%M:%S %Y')
    date_to_return = f'{date_filter.day}-{date_filter.month}-{date_filter.year}'
    
    return date_to_return


def sort_files(path_directory: str, file_list: List[Tuple]):
    """
    Lists the files in the sort directory
    Uses recursion to obtain files from subdirectories
    Copies files to a directory named according to their last modified date
    """

    content_dir: List[str] = os.listdir(path_directory)

    for filename in content_dir:
        path_file = os.sep.join([path_directory, filename])
        if os.path.isdir(path_file):
            sort_files(path_file, file_list)
        else:
            try:
                stats = os.stat(path_file)
                date = date_from_seconds(stats)
                file_list.append((path_directory, filename, date))
                os.makedirs(date, exist_ok=True)
                print(f'{path_directory}{filename}')
                shutil.copy(f'{path_directory}{filename}', f'{date}/{filename}')
            except Exception as _err:
                print(_err)
                continue


files: List[Tuple] = []
sort_files(SORT_DIR, files)
print(files)

输出：

编辑：来自 orlevii 的回答很有用..这是更正后的代码：

def sort_files(path_directory: str, file_list: List[Tuple]):
    """
    Lists the files in the sort directory
    Uses recursion to obtain files from subdirectories
    Copies files to a directory named according to their last modified date
    """

    for data in os.walk(SORT_DIR):
        dir_path, folders, files = data
        print(dir_path)
        print(files)
        for file in files:
            try:
                dir_for_stat = f'{dir_path}\{file}'
                stats = os.stat(dir_for_stat)
                date = date_from_seconds(stats)
                file_list.append((dir_path, file, date))
                os.makedirs(date, exist_ok=True)
                print(f'{dir_path}\{file}')
                shutil.copy(f'{dir_path}\{file}', f'{date}\{file}')
            except Exception as _err:
                print(_err)
