每次执行后使用不同的名称创建文件夹

如何解决每次执行后使用不同的名称创建文件夹

我正在尝试创建一个程序，该程序在每次执行时都在文件夹内创建一个名称不同的新文件夹。我粘贴了下面使用的代码：

import os


current_directory = os.getcwd()
name = "Day 1"


def folder_create(path,folder_name):
    folder_names = [folder for folder in os.listdir(
        path) if os.path.isdir(folder)]
    if folder_name not in folder_names:
        os.makedirs(folder_name)
    else:
        folder_num = folder_name.split(' ')[1]
        new_folder_name = f'Day {int(folder_num) + 1}'
        os.makedirs(new_folder_name,exist_ok=False)
        folder_name = new_folder_name
    return folder_name


if __name__ == '__main__':
    name = folder_create(current_directory,name)
    print(name)

此代码仅工作两次，这意味着它只能在执行两次后创建两个文件夹，即（第1天和第2天），但之后会给出FileExistError。请帮助我找到解决方法，因为我只希望它创建一个新文件夹，每次执行的第二天都命名为i，e（第1天，第2天，第3天）。

解决方法

此解决方案可能适合您-

import os
import random


current_directory = os.getcwd()
day_names = []

for i in range(0,10+1):  # 10 or Or Other Number+1 To Get Day Names That Number Of Times
    day_names.append('Day '+str(i))


def folder_create(path,folder_name):
    folder_names = [folder for folder in os.listdir(
        path) if os.path.isdir(folder)]
    if folder_name not in folder_names:
        os.makedirs(folder_name)
    else:
        folder_num = folder_name.split(' ')[1]
        new_folder_name = f'Day {int(folder_num) + random.randint(0,10000)}'  # To Get A Random Day Name If It Already Exixts
        os.makedirs(new_folder_name,exist_ok=False)
        folder_name = new_folder_name
    return folder_name


if __name__ == '__main__':
    for name in day_names:  # Looping To Get Each Day Name
        name = folder_create(current_directory,name)
        print(name)

,

这将很好地工作。代码的真正问题是，您一直在向folder_create()函数提供相同的“名称”参数。

我要做的就是消除提供name参数的需要。

它现在要做的是获取目录列表，对列表进行排序，然后使用负索引获取最后一个。然后使用最后一个创建新的文件夹名称。玩得开心

import os


current_directory = os.getcwd()
name = "Day 1"


def folder_create(path):
    folder_names = [folder for folder in os.listdir(
        path) if os.path.isdir(folder)]
    folder_names.sort()
    if "Day 1" not in folder_names:
        os.makedirs('Day 1')
    else:
        folder_num = folder_names[-1].split(' ')[1]
        new_folder_name = f'Day {int(folder_num) + 1}'
        os.makedirs(new_folder_name,exist_ok=False)
        folder_name = new_folder_name
    return folder_name


if __name__ == '__main__':
    name = folder_create(current_directory)
    print(name)
