#95263 — AttributeError

Hi Everyone,


What is the list equivalent to line 12: ncount.sort(reverse=True)


count = dict()
fname = raw_input("Enter file name: ")#
handle = open (fname, 'r')#
for line in handle: 
    if line.startswith("From "):
        address = line.split()[5] 
        line = line.rstrip()
        count[address] = count.get(address, 0) + 1 

for key,val in count.items():
    ncount = (key,val)
    ncount.sort(reverse=True)
    print key,val


Error message, reads: AttributeError, line 12, below : 'tuple' object has no attribute 'sort'

assign using () creates tuple not a list. Tuples have not .sort() method.
correct would be:
ncount = [key,val]

What are you trying to do? Why are you trying to sort a key/value pair 
in reverse order?

In that case, you want to sort the entire collection, not a single
key-value pair.

It seems to me you can do this fairly efficiently with collections.Counter.

import collections
with open(raw_input("Enter file name: ")) as f:
    counts = collections.Counter(line.split()[5].rstrip() for line in
f if line.startswith("From "))

counts = counts.items()
counts.sort()
for hour, count in counts:
    print hour, count

The most important part is getting items() and then sorting the whole thing.

Well, line.split()[5] isn't the address, it's the time, e.g. "09:14:16". 
You need to do just a little more work to extract the hour.

I don't know what you think you'll achieve by sorting key/value pairs in 
reverse order. What you should be doing is sorting the keys (hours), 
although sorting the pairs of keys and values (i.e., the items) would 
have the same effect. Have a look at the 'sorted' function.

#95272

Message heard loud and clear:

There are no error messages, the output is the issue.

Question: What sorted function should I write to produce the desired
output, below:

Desired output:

04 3
06 1
07 1
09 2
10 3
11 6
14 1
15 2
16 4
17 2
18 1
19 1

Latest revised code:

count = dict()
fname = raw_input("Enter file name: ")#
handle = open (fname, 'r')#
for line in handle:
    if line.startswith("From "):
        address = line.split()[5]
        line = line.rstrip()
        count[address] = count.get(address, 0) + 1

lst = list()
for key,val in count.items():
    lst.append( (val, key) )
    lst.sort(reverse=True)
    for val, key in lst[:12]:
        print key,val


Output code:

In [3]: %run assignment_10_2_v_01
Enter file name: mbox-short.txt

Instead of iterating over "count.items()", iterate over 
"sorted(count.items())".

I don't know why you have a nested 'for' loop; just iterate over the
sorted items and print them. Simple.

Me, I'd start by declaring a dictionary to hold the data:

counts = { "{:02d}".format(h):0 for h in range(24) }

Then I'd parse the strings in the log file(s), incrementing counts[x] 
where x is the hour field of the timestamp.

Then I'd create a list of tuples:

ncounts = [(k,v) for k,v in counts.items()]

sort it by the hour field:

ncounts.sort(key = lambda x: x[0])

and print it:

for x in ncounts:
    print x[0], x1

Read the indicated line _carefully_.

What is it _actually_ trying to split?

I'm baffled as to why you now have a nested 'for' loop 3 levels deep!

What should I look at assignment_10_2_v_06.py.:


handle = """From stephen.marquard@uct.ac.za Sat Jan  5 09:14:16 2008
>From louis@media.berkeley.edu Fri Jan  4 18:10:48 2008
""".split("\n")
# Snippet file data: mbox-short.txt

count = dict()
#fname = raw_input("Enter file name: ")# Add Snippet file
#handle = open (fname, 'r')# Add Snippet file
for line in handle:
    if line.startswith("From "):
        time = line.split() # Sort time

        hours = line.split(":")[5] # Sort hours
        line = line.rstrip()

        count[hours] = count.get(hours, 0) + 1 # counter

lst = [(val,key) for key,val in count.items()]

print key, val

You shouldn't. You should instead approach your tutor and tell him you 
are too stupid to learn computer programming[1], and can you please 
transfer to floor-scrubbing 101.

[1] You have repeatedly ignored advice and instructions that you have 
been given. This is de-facto proof that you are not capable of learning 
to program computers.

Ooooh!  I've heard stories people were released from *mart (or was that 
dell?) for comments like that.  :)

However-a-propos-ly y'rs,

Emile


@ltc -- read this -- then re-read all the responses you've been given. 
Repeat ad nauseam.  Until you can understand and incorporate advice 
given you're wasting your time and ours asking.
