(urllib.retrieve) files from a server without knowing the filenames?
For instance, there is smth like folder/spam.egg, folder/
unpredictable.egg and so on. If not, perhaps some kind of glob to
create a list of existing files? I'd really appreciate some help,
since I'm really out of my (newb) depth here.
You might try the os.path module and/or the glob module in the standard
python library.

>DiezHere's a function I wrote for checking remote or local file existence. It works for me but admittedly I haven't tested many cases with it. Also its currently specific to an http URI scheme.
def fileExists(self, fileUrlPath):
fileExists = False
if "http:" in fileUrlPath.lower():
#We don't want to open the file so ask the header if the
#file exists
urlParts = urlparse(fileUrlPath)
host = urlParts[1]
http = httplib.HTTP(host)
http.putrequest("HEAD", fileUrlPath)
http.putheader("Host", host)
http.endheaders()
errorcode, errormessage, headers = http.getreply()
if errorcode == 200:
fileExists = True
else:
fileExists = path.exists(fileUrlPath)
return fileExists
