I am having so much trouble in creating/adding to the files in python

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")

Getting errors:

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

I am trying to creating a new file while keeping a variable as input the filename that has to be generated in a directory other than than that of the current py file.

Help me with some example of multiple ways of creating file, adding to the existing files.

Answer 1

This means the directories you have provided don't exist.
also adding '/' would mean that you're looking for a directory.
so First you need to create the folder /SU . and not use forbidden folder name characters mentioned here What characters are forbidden in Windows and Linux directory names? which '/' in your dates include

Answer 2

You may use the replace command to change all / characters to - so that the file name will not be treated as sub-directory

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")
