There are numerous ways to achieve this, including a simple os.system() call to the sqlite3 utility if you have that installed, but here's roughly what I'd do from Python:

con = sqlite3.connect('mydatabase.db')
outfile = open('mydump.csv', 'wb')
outcsv = csv.writer(outfile)

# dump column titles (optional)
outcsv.writerow(x[0] for x in cursor.description)
# dump rows
outcsv.writerows(cursor.fetchall())

outfile.close()
