Hello again Munin,
First i'll start with a spanking!
Post your code like this:(or pick your favorite starter)
Py> def do_load(self, arg):
... sitefile = file('sitelist', 'r+', 1)
... while True:
... siteline = sitefile.readline()
... site_rawlist = siteline.split()
... sitelist[site_rawlist[0]] = site_rawlist[1:]
... if len(siteline) == 0:
... break
See how much nicer that is even if the newsfeed gets mangled it comes
out ok(mostly).
If I guess right it looks like you are trying disect a line that was
empty or only had one element.
If you check for line length first you might do better.
Py> def do_load(self, arg):
... sitefile = file('sitelist', 'r+', 1)
... while True:
... if len(siteline) == 0:
... break
... siteline = sitefile.readline()
... site_rawlist = siteline.split()
... sitelist[site_rawlist[0]] = site_rawlist[1:]
Ok next thing is this smells like you really are trying to reinvent a
sort of pickle.
If you don't know search for 'python pickle module'.
examples abound but here it is anyway:
Py> import pickle
Py> # Pickle a dictionary
Py> f = open('/tmp/mydata', 'wb')
Py> f.write(pickle.dumps(yourdict)
Py> f.close()
Py> # and it is easy to get back as well
Py> f = open('tmp/mydata', rb')
Py> pdata = f.read()
Py> f.close()
Py> yourdict = pickle.load(pdata)
