[Baypiggies] urllib2 query

[Vikram K]

consider the following ftp site:
ftp://ftp.ncbi.nih.gov/refseq/H_sapiens/

I wish to write a program using urllib2 which can automatically download all
the contents of one of the folders in this site (say, for example,
mRNA_Prot) into a folder in my computer. Subsequently i want my program to
be able to automatically update the downloaded folder in my computer in
accordance with any changes made in future in the folder in the ftp site.
Any suggestions on how i should proceed?
I am using a windows 7 computer. Will i also have to use the scheduled tasks
option in system tools for solving this problem?
