a question about my script
Hi all,I am trying to get some files from an ftp site by ftplib module and I wrote the below script. However I have a problem. With my script, I login to ftp.genome.jp site. then, I am changing the directory to pub/kegg/genomes/afm and I am downloading "a.fumigatus.pep"
file. However, what I want is to connect pub/kegg/genomes
directory and in this directory there are 3 letters name files e.g. 'afm' and in each of these 3 letters files there is a file with the extension of '.pep' like a.fumigatus.pep. I want to get these '.pep' files from the 3 letter named files. If you help me I will be very glad. Thanks you in advance.Regards,Alperfrom ftplib import FTP def handleDownload( block): file.write(block) print ".",ftp = FTP('ftp.genome. jp') print ftp.login() directory = 'pub/kegg/genomes/ afm' print 'Changing to ' + directoryftp.cwd(directory) ftp.retrlines( 'LIST') filename = 'a.fumigatus. pep' print 'Opening local file ' + filenamefile = open(filename, 'wb') print 'Getting ' + filenameftp.retrbinary( 'RETR ' + filename, handleDownload) print 'Closing file ' +
