Help with delete_by_date. Works fine on my local machine. TypeError: remove: illegal type for path parameter in the Tree

Getting the following output from the Treehosue console when I run this code.

Works perfectly on my local machine

purging.py 
import os
import re

def delete_by_date(date):
    regex = '(?P<date>\d{4}\-\d{2}\-\d{2})'
    for item in os.scandir('backups'):
        match = re.search(regex, item.name)
        for match in match.groups():
            if match == date:
                os.remove(item)

The value in "item" was set from a call to "os.scandir", so it contains an "os.DirEntry" object. But the "os.remove" function takes a path argument. You might get that from object's "path" property.

Did this actually remove items on your local system? Or did it just run when there were no matching items?

HI Steven,

Yes I set up a dummy 'backups' folder on my system and it deleted the files with the corresponding date.

Will see if I can modify the code so I'm passing a path into os.remove()

Thanks for the feedback!
