Check For A File And Then Move It (Python)

Imagine that you have a folder that you periodically check for a file (i.e. a network share where colleagues drop a file throughout the day) and when the file exists you have to move it and log when it was moved.

I’m looking to tackle this today using Python. I’ve set myself the following outcomes that I want from the program:

read variables from a config file
check for a particular file
rename and move that file –
email the file to a particular address
log that is has moved the file (inc date/time and name)

geektechstuff_python_file_check_and_move — File Check and Move – initial ideas

After a little playing with the initial ideas during my lunch break, I got home and added in more detail.

geektechstuff_file_check_and_move — File Check and Move starts to look better

I temporarily added a time delay to the beginning of the program to show the log file entries.

If you want to see the program it is available on my GitHub (https://github.com/geektechdude/file_mover/tree/file_check_and_move):

email_settings.py – contains the settings you need to configure for email to work
file_check.py – is the Python program that controls the action
log_file.txt – is where the log entries are wrote to

My folder set up for testing my program looks like this:

# geektechstuff

# Python program to check if a file is in a folder and then carry out actions

# libraries to import

# date/time for timestamp

from datetime import datetime

# OS to interact with operating system

import os

# shutil to copy/move file

import shutil

# smtp lib to send email

import smtplib

# variables

file_name = “test.txt”

file_location = os.path.expanduser(“~/Desktop/respond_to_file_project/folder_to_check/”)

mv_file_name = “”

mv_file_location = os.path.expanduser(“~/Desktop/respond_to_file_project/files_that_have_been_found/”)

log_file_location = os.path.expanduser(“~/Desktop/respond_to_file_project/”)

log_value = “”

# settings for email, read from a file called “email_settings” located in same directory as program

from email_settings import smtp_server, port, login_user, login_pass, from_address, to_address

smtpObj = smtplib.SMTP_SSL(smtp_server, port)

smtpObj.login(login_user, login_pass)

# program

os.chdir(file_location)

time_stamp = datetime.now().strftime(‘%Y-%m-%d %H-%M-%S’)

for filename in os.listdir(“.”):

if filename == file_name:

print(“File Found”)

mv_file_name = time_stamp+”_”+file_name

os.rename(file_name,mv_file_name)

shutil.move(mv_file_name,mv_file_location)

print(“File moved and renamed”, mv_file_name)

# send email

email_msg = “File detected, moved and renamed: ” +mv_file_name

email_msg = str(email_msg)

smtpObj.sendmail(from_address, to_address,

‘From: FROM_EMAIL_ADDRESS\nSubject: File Detected ‘+ mv_file_name+’\n\n’+ email_msg)

smtpObj.quit()

log_value = 1

else:

print(“No file found matching”, file_name)

log_value = 2

# write to a log file

if log_value == 1:

os.chdir(log_file_location)

withopen(‘log_file.txt’,’a’) as filehandle:

filehandle.write(time_stamp+” File detected”+”\n”)

log_value = “”

elif log_value == 2:

os.chdir(log_file_location)

withopen(‘log_file.txt’,’a’) as filehandle:

filehandle.write(time_stamp+” File not detected”+”\n”)

log_value = “”
