Python • Re: Python and FTP not working

First: the FTP issue. It won't do anything, so I just wanted to see what happens when I execute this small script:

Code:

import ftplibfrom ftplib import FTPsession = ftplib.FTP('ftp.nluug.nl')FTP.size('README.nluug')FTP.quit()

nluug is an anynomous FTP server that is good for testing.

So many issues in 5 lines of code...


I don't have time to itemize/explain them all.


Perhaps this worked example will help -

Code:

When I try to run your code:

On windows I get no return and on my pi I get this:

^CTraceback (most recent call last):
File "/home/pi/ftp3.py", line 2, in <module>
remote = FTP('ftp.nluug.nl')
File "/usr/lib/python3.9/ftplib.py", line 119, in __init__
self.connect(host)
File "/usr/lib/python3.9/ftplib.py", line 156, in connect
self.sock = socket.create_connection((self.host, self.port), self.timeout,
File "/usr/lib/python3.9/socket.py", line 831, in create_connection
sock.connect(sa)
KeyboardInterrupt

Can somebody please explain how to start? I have no idea what I am doing wrong and how to learn this stuff. I have googled for hours, but can't find good, explainable resources. What I need is the level of "how to boil an egg?" that explains what an egg is, what a pan is, what water is, how to get the egg in the pan, how to get water in the pan etc.

Most resources just write: put egg in boiling water for 5 minutes.

Why did you change "session =" for "remote =" for example? What do both do, when do I use one, when the other? Why is mine wrong?
