Re: a question about my script

Hi,

I changed the script as you wrote below:

from ftplib import FTP

def handleDownload(block):
    file.write(block)
    print ".",

ftp = FTP('ftp.genome.jp')

print ftp.login()

directory = 'pub/kegg/genomes'
ftp.cwd(directory)

k=0
for direct in ftp.nlst():
    curdir = '%s/%s' % (directory, direct)
    ftp.cwd(curdir)
    for filename in ftp.nlst():
        if not filename.endswith('.pep'): continue
        file = open(filename, 'wb')
        ftp.retrbinary('RETR %s/%s' % (curdir, filename), handleDownload)
        file.close()
    k=k+1

print ftp.close()

However, it gave the same error message:

230 Anonymous access granted, restrictions apply.
Traceback (most recent call last):
File "ftp1.0.py", line 18, in ?
    ftp.cwd(curdir)
File "/usr/lib/python2.4/ftplib.py", line 494, in cwd
    return self.voidcmd(cmd)
File "/usr/lib/python2.4/ftplib.py", line 246, in voidcmd
    return self.voidresp()
File "/usr/lib/python2.4/ftplib.py", line 221, in voidresp
    resp = self.getresp()
File "/usr/lib/python2.4/ftplib.py", line 216, in getresp
    raise error_perm, resp
ftplib.error_perm: 550 pub/kegg/genomes/aae: No such file or directory

However, in ftp.genome.jp/pub/kegg/genomes/ site, there is 'aae' directory. What can be the reason?

regards,
alper

3 letters *files*? or 3 letters *directories*?

Do a cwd() starting one level above (that is, pub/kegg/genomes);
using ftp.dir() you can get the subdirectories, then iterate over all
of them, using another dir() to find the .pep files needed.

>directory = 'pub/kegg/genomes/ afm'

Is that whitespace intentional?

(If you just want to download the files and don't need really a
Python script, try wget...)
