创建有效的目录字符串并创建文件夹

Question

使用 string 和 string_2 正确打印字符串，但是当我想创建文件夹时，出现 [WinError 3] 错误：系统找不到正确的路径，mkdir 函数中的字符串突然有双 \
我的目标是根据当前日期创建一个文件夹

打印字符串时的结果
C:\Users\Albert\Desktop bc�3�3.06
C:\Users\Albert\Desktop bc�3�3.06

代码

import os
from datetime import datetime
import shutil


def archive_machine():
    date=datetime.now()
    date_correct_format = date.strftime('%Y-%m-%d')
    date_correct_format_month = date.strftime('%Y.%m')
    date_correct_format_year = date.strftime('%Y')
    file_name = 'Sales Tracker - archived version' + date_correct_format
    string = r'C:\Users\Albert\Desktop\abc'+'\\'+date_correct_format_year+'\\'+date_correct_format_month
    string_2 = r'C:\Users\Albert\Desktop\abc'+f'\{date_correct_format_year}'+f'\\'+f'{date_correct_format_month}'
    #print(string)
    #print(string_2)
    os.mkdir(string)
    os.mkdir(string_2)

archive_machine()

以下内容对您有用吗？ 基本上获取您想要传递的字符串（将 C:\Users\Desktop 位保留为标准，因为不想错误地创建另一个这样的目录！）并循环遍历它的每个元素以确保您拥有完整的目录路径已创建。

您可能需要先安装pathlib，如下所示

pip install pathlib

from pathlib import Path
from datetime import datetime

def path_check(dir_path,set_string):

    def path_creation(dir_path):
        # check if path given is currently a directory
        # if it is move on, if not then create the directory passed
        if Path(dir_path).is_dir():
            print('directory already there')
        else:
            print('missing directory, creating now')
            Path(dir_path).mkdir()
    
    # holder for already made paths
    made_paths = []
    # loop through needed directories given in string
    for s in dir_path.split(sep='\\'):
        made_paths.append(s)
        path_to_make = '\\'.join(made_paths)
        path_creation(path_to_make)


def archive_machine():
    date=datetime.now()
    date_correct_format = date.strftime('%Y-%m-%d')
    date_correct_format_month = date.strftime('%Y.%m')
    date_correct_format_year = date.strftime('%Y')
    file_name = f'Sales Tracker - archived version {date_correct_format}'
    set_string = 'C:\\Users\\Albert\\Desktop\\'
    string = f'abc\{date_correct_format_year}\{date_correct_format_month}'
    path_check(string,set_string )

archive_machine()
