How to make Python check if ftp directory exists?

Question

I\'m using this script to connect to sample ftp server and list available directories:

from ftplib import FTP
ftp = FTP(\'ftp.cwi.nl\')   # connect to host, defa

The examples attached to ghostdog74's answer have a bit of a bug: the list you get back is the whole line of the response, so you get something like

drwxrwxrwx    4 5063     5063         4096 Sep 13 20:00 resized

This means if your directory name is something like '50' (which is was in my case), you'll get a false positive. I modified the code to handle this:

def directory_exists_here(self, directory_name):
    filelist = []
    self.ftp.retrlines('LIST',filelist.append)
    for f in filelist:
        if f.split()[-1] == directory_name:
            return True
    return False

N.B., this is inside an FTP wrapper class I wrote and self.ftp is the actual FTP connection.
