Outputting timestamps from a list of files

Question

I'm having problems outputting timestamps for files in a directory. Want to list timestamps if they reach a certain time window, currently can't even get output. Not sure what I am doing wrong and hitting a wall atm

from datetime import datetime, timedelta
from os import scandir

DIR = "/home/user/directory"
TIME_FORMAT = "%Y-%m-%d%H:%M:%S.%fZ"


def convert_timestamps():
    """converting timestamps to human readable"""
    # timestamp = datetime.utcnow() - timedelta(days=7)
    timestamp = datetime.utcfromtimestamp
    file_times = timestamp.strftime(TIME_FORMAT)
    return file_times

def get_files():
"""getting files from dir"""
    dir_filenames = scandir(DIR)
    for filename in dir_filenames:
        if filename.is_file():
            file_stat = os.stat(str(filename))
            # info = os.stat(filename)
            print("Last Modified time: {}".format(filename.name, convert_timestamps(file_stat.st_mtime)))



if __name__ == 'main':
    get_files()

The following snippet works, but is obviously not much of a program

DIR = "/home/user/directory"
TIME_FORMAT = "%Y-%m-%d%H:%M:%S.%fZ"


file_stat = os.stat(DIR)
timestamp = datetime.utcnow() - timedelta(days=7)
file_times = timestamp.strftime(TIME_FORMAT)
print("Last mod time are: ", file_times)

Answer 1

The main issue was the module name. You need to check for __main__, not main. You also were not passing any parameter to the convert_timestamps function.

This code should work:

from datetime import datetime, timedelta
from os import scandir
import os

DIR = "C:/tmp"  #"/home/user/directory"
TIME_FORMAT = "%Y-%m-%d %H:%M:%S.%fZ"


def convert_timestamps(stmp):
    """converting timestamps to human readable"""
    # timestamp = datetime.utcnow() - timedelta(days=7)
    timestamp = datetime.utcfromtimestamp(stmp)
    file_times = timestamp.strftime(TIME_FORMAT)
    return file_times

def get_files():
    """getting files from dir"""
    dir_filenames = scandir(DIR)
    for filename in dir_filenames:
        if filename.is_file():
            file_stat = os.stat(filename)
            # info = os.stat(filename)
            print("{} \tLast Modified time: {}".format(filename.name, convert_timestamps(file_stat.st_mtime)))

if __name__ == '__main__':   # must be __main__
    get_files()

Output
