Python Python for File Systems Manipulation Daily Backup

Not sure why this doesn't work. Seems to work fine on my machine.

Is there and edge case that I am missing here? I assume all the date inputs are valid dates, as I'm not told what error to raise if the date is invalid. I tried this on my machine and it seems to work just fine for either date format. Any help is appreciated.

backup.py 
import os

def create_daily_dir (date_str):
    a, b, c = date_str.split("-")
    if len(a) == 4:
        y, m, d = int(a), int(b), int(c)
    else:
        m, d, y, = int(a), int(b), int(c)   
    dir_name = "{}-{:02d}-{:02}".format(y, m, d)   

    os.makedirs(dir_name, exist_ok=True)

Hi leakedmemory,

Nice solution. You are very close. I think you are being thrown off by the same thing that I was.

The 'financial' directory is not the current working directory, it is inside the current working directory. I misread this instruction at first.

So you will just need to make sure to supply the full path, eg., "financial/YYYY-MM-DD", in your final line. Other than that, your code works.

import os

def create_daily_dir (date_str):
    a, b, c = date_str.split("-")
    if len(a) == 4:
        y, m, d = int(a), int(b), int(c)
    else:
        m, d, y, = int(a), int(b), int(c)   
    dir_name = "{}-{:02d}-{:02}".format(y, m, d)   

    os.makedirs(os.path.join('financial', dir_name), exist_ok=True)

That did the trick. Thanks!
