How do I download a zip file in python using urllib2?

Viewed 56259

Two part question. I am trying to download multiple archived Cory Doctorow podcasts from the internet archive. The old one's that do not come into my iTunes feed. I have written the script but the downloaded files are not properly formatted.

Q1 - What do I change to download the zip mp3 files? Q2 - What is a better way to pass the variables into URL?

 # and the base url.

def dlfile(file_name,file_mode,base_url):
    from urllib2 import Request, urlopen, URLError, HTTPError

    #create the url and the request
    url = base_url + file_name + mid_url + file_name + end_url 
    req = Request(url)

    # Open the url
    try:
        f = urlopen(req)
        print "downloading " + url

        # Open our local file for writing
        local_file = open(file_name, "wb" + file_mode)
        #Write to our local file
        local_file.write(f.read())
        local_file.close()

    #handle errors
    except HTTPError, e:
        print "HTTP Error:",e.code , url
    except URLError, e:
        print "URL Error:",e.reason , url

# Set the range 
var_range = range(150,153)

# Iterate over image ranges
for index in var_range:

    base_url = 'http://www.archive.org/download/Cory_Doctorow_Podcast_'
    mid_url = '/Cory_Doctorow_Podcast_'
    end_url = '_64kb_mp3.zip'
    #create file name based on known pattern
    file_name =  str(index) 
    dlfile(file_name,"wb",base_url
