How to determine if mp3 file was downloaded and replace it?

Question

Is there a way to determine if an mp3 file was downloaded on PC and to replace it to another folder?
For example - I downloaded a new song. It was downloaded to the Downloads folder, but I want to automatically replace the song to the Music folder.
Is it possible with Python?

You can do this by using the builtin "os" library in python.

import os
from os import path

file_to_check = "somefile.mp3"

from_path = "~/Downloads/" + file_to_check
to_path = "~/Music/" + file_to_check

if path.exists(from_path):
    os.rename(from_path, to_path)

(EDIT based on comment) In the case you don't know the name of the file this would work by moving all .mp3 files to the Music folder:

for song_file in os.listdir("Downloads/"):
    if song_file.endswith(".mp3"):
        os.rename("Music/" + song_file)

What if I don't know the name of the `mp3` file? – Alex Zab Dec 20 '20 at 15:40

Can you provide a bit more detail are you searching for all mp3 files and moving them? – Aasim Sani Dec 20 '20 at 15:42
My idea is when `mp3` file downloaded it must be replaced. Doesn't matter what name of this file and how many files – Alex Zab Dec 20 '20 at 15:46
Added how to do that to the answer. – Aasim Sani Dec 20 '20 at 15:48
I'll put it in `while True` so they will move anytime – Alex Zab Dec 20 '20 at 15:49
While that can work it is not the best practice. You can you use the `datetime` library to make it run at a fixed interval. [Example here](https://stackoverflow.com/questions/15088037/python-script-to-do-something-at-the-same-time-every-day) – Aasim Sani Dec 20 '20 at 15:54

The pathlib will have all the functionality you need.

Here is an example:

from pathlib import Path

source = Path('path_to_source_mp3')
dest = Path('path_to_dest_mp3')

if source.exists():
    source.replace(dest)

you can list your files with `os.listdir()` – Lior Cohen Dec 20 '20 at 15:42

The final code is -

import os
from os import path

from_path = 'C:/Users/username/Downloads/'

for file in os.listdir(from_path):
    if file.endswith('.mp3'):
        from_path = 'C:/Users/username/Downloads/' + file
        to_path = 'C:/Users/username/Music/' + file

        os.rename(from_path, to_path)

        print("Moved")
