我在创建/添加到 python 中的文件时遇到了很多麻烦

Question

date = input("Enter today's date: ")
mood = input("How do you rate your mood today from 1 to 10? ")
thought = input("Lets your thought flow :" + "\n")

with open(f"../SU/{date}.txt", 'w') as file:
    file.write(mood + 2 * "\n")
    file.write(thought + 2 * "\n")

获取错误：

C:\Users\User\Desktop\PyPro_Jan23_3.10\venv\Scripts\python.exe C:\Users\User\Desktop\PyPro_Jan23_3.10\Bonus\Bonuss8.py 
Enter today's date: 2023/01/01
How do you rate your mood today from 1 to 10? 10
Lets your thought flwo :
fine
Traceback (most recent call last):
  File "C:\Users\User\Desktop\PyPro_Jan23_3.10\Bonus\Bonuss8.py", line 5, in <module>
    with open(f"../SU/{date}.txt", 'w') as file:
FileNotFoundError: [Errno 2] No such file or directory: '../SU/2023/01/01.txt'

Process finished with exit code 1

我正在尝试创建一个新文件，同时将一个变量作为输入，该文件名必须在当前 py 文件以外的目录中生成。

帮我举一些创建文件、添加到现有文件的方法的例子。

Answer 1

这意味着您提供的目录不存在。
还添加 '/' 将意味着您正在寻找一个目录。
所以首先你需要创建文件夹/SU 。 and not use forbidden folder name characters mentioned here Windows 和 Linux 目录名称中禁止使用哪些字符？ 您日期中的哪个“/”包括

Answer 2

您可以使用替换命令将所有/字符更改为-这样文件名就不会被视为子目录

date = input("Enter today's date: ")
mood = input("How do you rate your mood today from 1 to 10? ")
thought = input("Lets your thought flow :" + "\n")

date = date.replace("/", "-")

with open(f"../SU/{date}.txt", 'w') as file:
    file.write(mood + 2 * "\n")
    file.write(thought + 2 * "\n")
