This Python script will connect to a Deluge deamon running on localhost, and generate a summarized status of active torrents.

torrent-info.py

import os

The command "deluge-console info" generates this output:

/home/pi$ deluge-console info

This output is then parsed, and only active downloading torrents are shown:

 $ sudo python torrent-info.py

It contains the following information:
[Total size] [Torrent name]
[Completed %] [Download speed] [ETA]

'''
p = os.popen("su - deluge-user -c \"deluge-console info\"") #deluge-user is a username with access to deluge-console
q = p.read()
p.close()
r = q.split(" \n");

for torrent in r:
    if (torrent.find("State: Downloading") >= 0):
        s = torrent.split("\n")
        name = s[0][6:]
        down = s[2][31:]
        down = down[:down.find("/s Up")]
        down = down.split(" ")
	down = str(int(float(down[0]))) + down[1]
        eta = s[2][s[2].find("ETA: ")+5:]
        total = s[4]
        total = total[total.find("/") + 1:]
        total = total[:total.find(" Ratio")]
	total = total.replace("iB","").replace(" ","")
        percent = s[7][10:]
	percent = percent[:percent.find(" ")].replace("%","")
	percent = str(int(float(percent))) + "%"
        summary = "%s | %sbps | %s" % (percent, down, eta)
        summary = summary.replace("iB","").replace(" ","").replace("|"," ")
        print total + " " + name
        print summary
        print "==="

If the download speed is zero, "ETA: " will be missing from the deluge-console output, so eta will contain bad text. I suggest replacing line 53 with:

if s[2].find("ETA: ") > -1:
    eta = s[2][s[2].find("ETA: ")+5:]
else:
    eta = '∞'

If you use the infinity symbol, you'll need to add # -*- coding: utf-8 -*- to the top of the file.
