PYTHON - UNRAR : how can I build a thread to monitoring the downloading status

[Palerm0_24]

Hello to all of you,

I am posting this discussion because I have a problem. Indeed, I'm new to python and I'd like to get help on Threading.
I am currently developing an automation script to connect to an FTP, navigate to folders and download files.
This part is indeed finished but I would like to be able to make a thread to check for example (every 20min) if the download is going smoothly.

here is my download code:

class Download:

  def __init__(self):
    self.path="FolderFiles"
    self.target=" /var/www/folder/Output"

  def downloadFile(self):
    for root, dirs, files in os.walk(self.path, topdown=False):
      for name in files:
        print(name)
        rarFiles=os.path.join(root, name)
        unrar = "unrar x -y "+rarFiles+self.target
      os.system(unrar)
          #time.sleep(10)

PS: If you have other proposals other than Thread I am also listening
Thank you for your help

Be aware that if you're ftp is from one server, you may get kicked off if you increase speed too much.
That being said, you may want to look at multiprocessing: https://docs.python.org/3.4/library/mult...ssing.html
Threading works well when you have idle CPU time, but not so when doing intensive things like downloading.
Multiprocessing is true parallel processing.

After lot of test, I decided to work in this way: analyse the files after downloading in function of size, downloading time etc...
The unrar library cannot provides any solutions to test the good process during the downloading

Thank for your help
