python ftplib weird behaviour

Question

I'm running into some very strange behaviour when trying to connect to a ftp server using ftplib. What I'm doing is:

import ftplib
ftp = ftplib.FTP('my-ftp-server')
ftp.login('user ', 'pass')

Now if I run these from a python interpreter it work fine and I get:

'230 Login successful.'

But I want to have these in a nice script that can do stuff for me. When I put these all in some python script and run:

 python my_ftp_stuff.py

I get:

 ftplib.error_perm: 530 Login incorrect.

I really am clueless as to what can cause this weird behaviour. Does anyone have any tips on what to try?

Best regards

Answer 1

You have a space (' ') character in your username field.

Answer 2

You should pass login & password to __init__ instead of login method:

import ftplib
ftp = ftplib.FTP('my-ftp-server', 'login', 'password')
print(ftp.dir())
