This is for the purging python challenge in Python File System. Not really sure why this answer is not working.

import os import re

def delete_by_date(date_string): dir_list = os.listdir() for i in dir_list: if date_string in i: os.remove(i) else: continue

purging.py 
import os
import re

def delete_by_date(date_string):
    dir_list = os.listdir()
    for i in dir_list:
        if date_string in i:
            os.remove(i)
        else:
            continue

This is what worked for me:

import os

def delete_by_date(date_string):
    for entry in os.scandir('backups'):
        if entry.is_file() and date_string in entry.name:
            os.remove(entry.path)
    return

Speaking from experience, testing whether or not an entry is a file is important.

Also, it wasn't enough to is iff date_string was in entry. It has to be in entry.name.

Thank you very much Stephen, that works nicely. And thanks for the tip about checking that entry is a file, much appreciated
