Hello,
I am completely new to python and I have question that I unfortunately
could not find in the various documentation online. My best guess is
that the answer should be quitte easy but I have just enterd the learning
phase so that means a hightend chance for stupidity and mistakes on my
part.
I am trying to fill a nested dictionary from parsing a logfile. However
each time there is only one key entry created and that's it. Just
one entry, while the keys are different. That's 100% sure. I think
therefore that it is an assignment error in my part. [there we have it...]
To give an static example of the datastructure that I am using to clear
any confusion on the datastructure part:
records = { 'fam/jason-a' : {
'date' : 'Fri Sep 8 16:45:55 2006',
'from' : 'jason',
'subject' : 'Re: Oh my goes.....',
'msize' : '237284' },
'university/solar-system' : {
'date' : 'Fri Sep 8 16:45:46 2006',
'from' : 'jd',
'subject' : 'Vacancies for students',
'msize' : '9387' }
}
Looping over this datastructure is no problem.
rkeys = ['date', 'from', 'subject', 'msize']
for folder in records.keys():
print '--'
print folder
for key in rkeys:
print records[folder][key]
Now for the actual program/dynamic part - assignment in the loop I use the
following function. Note `datum' is not a date object, just a string.
def parselog(data):
other = 0
records = {}
for line in string.split(data, '\n'):
str = line.strip()
if str[:4] == 'From':
mfrom, datum = extrfrom(str), extrdate(str)
print datum, mfrom
elif str[:4] == 'Fold':
folder = extrfolder(str[8:])
records = {folder : { 'date' : datum, 'mesgbytes' :
extrmsize(str[8:]), 'mesgcount' : 1}}
else:
other += 1
displrec(records)
Note, this is not ment as a collision type datastructure, all initial data
entries are unique. My question: Where is my assignment e.g. records =
{folder.... wrong ?
Thankx in advance for any tips, hints and answers.
Cheers,
Jason.
