Python select last 12 hours new generated files in a folder

Question

I am trying to get all files for last 12 hours, file names and the list have following format:

C:\myproject\Attendance_aaa_2021-07-22-4hr.csv     07/22/2021 04:20 AM Modified
C:\myproject\Attendance_bbb_2021-07-23-16hr.csv    07/23/2021 16:20 PM Modified
C:\myproject\Attendance_ccc_2021-07-26-4hr.csv     07/26/2021 04:15 AM Modified
C:\myproject\Attendance_ddd_2021-07-26-16h.csv     07/26/2021 16:15 AM Modified
C:\myproject\Attendance_eee_2021-07-26-16h.csv     07/26/2021 16:35 AM Modified

This is my code:

import os
path_dataset = r'C:\myproject\'

def get_file(path_dataset):
     files = os.listdir(path_dataset) #check file list
     files.sort() #sort file
     file_list = []
     for file in files:
         if (file.startswith("Attendance")) & (file.endswith(".csv")):
              f_name = str(file) 
              tr = '\\'
              filename = path_dataset + tr + f_name
              file_list.append(filename)
                  
     return (file_list)


get_file(path_dataset)

However, this code will return all files in the folder. I'm thinking to use below code to identify the file modified time:

last12HourDateTime = datetime.today() - timedelta(hours = 12)

So that all files with last 12 hours from now on will be listed in my file_list. Could anybody help with this, how to integrate the time sorting for file list? Much appreciated!

Answer 1

import os
import time
path_dataset = 'C:\\myproject\\'
twelve = time.time() - 12 * 60 * 60

def get_file(path_dataset):
     files = os.listdir(path_dataset) #check file list
     file_list = []
     for file in files:
         path = path.dataset + "\\" + file
         if file.startswith("Attendance") and file.endswith(".csv") and os.path.getmtime(path) > twelve:
              file_list.append(path)
     return file_list

print(get_file(path_dataset))
