Re: [Tutor] AttributeError,
Hi Steven,
Message heard loud and clear:
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

[Tutor] AttributeError,
Hi Everyone,
Why is there an AttributeError, line 12, below : 'tuple' object has no
attribute 'sort'?
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

Re: [Tutor] Dictionary Issue
Alan,
I want to find the max val , keys and values are defined on line 10:
for kee, val in count.items():
Then, maxval determines the max value on line 11:
if val > maxval:
right, view a copy of the revised code at
http://tinyurl.com/nvzdw8k
Question1: are these assumptions true, above?
Question2: dict maps strings into keys and values?

Mark, I'm following the instructor's video exercise, available at https://www.youtube.com/watch?v=3cwXN5_3K6Q. View attached screen shot file, image file shows a copy of the counter: cou[wrd] =cou.get(wrd,0) +1 Please, explain the differences in counter methods?

Hi Alan,
Questions(1):Why does print line, prints blank space; and, (2) print
address prints a single email address:
View print results as follows:
In [70]: %run assignment_9_4_24.py
Enter file name: mbox-short.txt
r...@media.berkeley.edu 1
In [71]: print handle

Re: [Tutor] Dictionary Issue
On my breath and soul, I did:
Counter objects have a dictionary interface except that they return a zero
count for missing items instead of raising a KeyError

Re: [Tutor] Dictionary Issue
Hi Alan,
I moved counter outside the loop and below dict, maxval = None
maxkee = None are both positioned outside the loop.
URL link to the revisions are available at http://tinyurl.com/nvzdw8k
Question: How do I define Counter
Revised code reads:
fname = raw_input("Enter file name: ")
handle = open (fname, 'r')
counter = dict ()
c = Counter(['address'])
maxval = None
maxkee = None
for line in handle:
if line.startswith("From: "):
address = line.split()[1]
for maxkee, val in c.items():
maxval = val
maxkee = kee
print maxkee and maxval
Traceback message reads:
NameError
Traceback (most recent call last)
C:\Users\vm\Desktop\apps\docs\Python\assignment_9_4_16.py in ()
3
4 counter = dict ()
> 5 c = Counter(['address'])
6
7 maxval = None
NameError: name 'Counter' is not defined

Re: [Tutor] Dictionary Issue
Hi Alan
The output as reported by the latest code revision: c...@iupui.edu 1 ←
Mismatch
Looks like python continues to print the wrong data set:
In [11]: print val
1 In [12]: print kee r...@media.berkeley.edu In [13]: print address
c...@iupui.edu
In order to complete the assignment, using data from the source file,
python must print the email address of the maximum sender and the number
of sends, i.e., c...@iupui.edu 5
I think the problem is in the placement of the counter?
Question: What is the source of the dictionary keys and values:
maxval = None
maxkee = None
Here is the latest revised code as follows:
fname = raw_input("Enter file name: ")
handle = open (fname, 'r')
count = dict ()
for line in handle:
if line.startswith("From: "):
address = line.split()[1]
count[address]= count.get(address,0) +1
maxval = None
maxkee = None
for kee, val in count.items():
maxval = val
maxkee = kee
print address, val

Re: [Tutor] Dictionary Issue
Hi Mark,
Address identifies the email address with the maximum number of sends:
c...@iupui.edu.
Secondly, we are missing a count on the number of messages sent by
c...@iupui.edu, i.e., 5.
Thirdly, maxval 'none' is not defined on line # 24
Questions: How do we define the value of none for the key maxval and
retrieve a number count on the number of messages sent by c...@iupui.edu.

[Tutor] Dictionary Issue
Hi everyone:
I want to write a python program that reads through the data file of
mbox-short.txt.Mbox-short.txt, i.e., download is available at
http://www.py4inf.com/code/mbox-short.txt.
Secondly, I want for python to figure out who sent the greatest number of
mail messages.
The output should read: c...@iupui.edu 5
However, there is a traceback message:
In [40]: %run 9_4_4.py
File "C:\Users\vm\Desktop\apps\docs\Python\_9_4_4.py", line 19
count = dict()
^
SyntaxError: invalid syntax
Raw data code reads:
fname = raw_input("Enter file name: ")
handle = open (fname, 'r')
text = handle.read()
## The program looks for 'From ' lines and takes the second
## word of those lines as the person who sent the mail.
addresses = set()
for addr in [ text.split()[2]('From ')
if fromline
## The program creates a Python dictionary that maps
## the sender's mail address to a count of the number
## of times they appear in the file.
count = dict()
for wrd in word:
count[wrd]= count.get(wrd,0) +1
## After the dictionary is produced, the program reads
## through the dictionary using a maximum loop to
## find the greatest number of mail messages.

Re: [Tutor] String Attribute
Hi Alan,
Question1: Why did the following strip function fail: line2 =
line.strip (',')
View instructions for 'str.strip([*chars*])¶
<https://docs.python.org/2.7/library/stdtypes.html?highlight=strip#str.strip>'
which is available at
https://docs.pythonorg/2.7/library/stdtypes.html?highlight=strip#str.strip
Question2: How do I code a vertical column output
Revised code:
fname = raw_input("Enter file name: ")
if len(fname) < 1 : fname = "mbox-short.txt"
fh = open(fname)
count = 0
addresses =[]
for line in fh:
if line.startswith('From'):
line2 = line.strip ()
line3 = line2.split()
line4 = line3[1]
addresses.append(line4)
count = count + 1
print addresses
print "There were", count, "lines in the file with From as the first word"

Re: [Tutor] String Attribute
Hi Emile,
I made a mistake and incorrectly assumed that differences between 54 lines
of output and 27 lines of output is the result of removing duplicate email
addresses, i.e., gsil...@umich.edu
gsil...@umich.edu, c...@iupui.edu, c...@iupui.edu
Apparently, this is not the case and I was wrong :(
The solution to the problem is in the desired line output:

Re: [Tutor] String Attribute
Hi Alan,
I made a mistake and incorrectly assumed that differences between 54 lines
of output and 27 lines of output is the result of removing duplicate email
addresses, i.e., gsil...@umich.edu
gsil...@umich.edu, c...@iupui.edu, c...@iupui.edu
Apparently, this is not the case and I was wrong :(
The solution to the problem is in the desired line output:
stephen.marqu...@uct.ac.za

Re: [Tutor] String Attribute
Hi Alan,
Question1: The output result is an address or line?
Question2: Why are there 54 lines as compared to 27 line in the desired
output?
Here is the latest revised code:
fname = raw_input("Enter file name: ")
if len(fname) < 1 : fname = "mbox-short.txt"
fh = open(fname)
count = 0
addresses = set()
for line in fh:
if line.startswith('From'):
line2 = line.strip()
line3 = line2.split()
line4 = line3[1]
addresses.add(line4)
count = count + 1
print addresses
print "There were", count, "lines in the file with From as the first word"
The output result:
set(['stephen.marqu...@uct.ac.za', 'lo...@media.berkeley.edu', '
zq...@umich.edu', 'rjl...@iupui.edu', 'c...@iupui.edu', 'gsil...@umich.edu',
'wagne...@iupui.edu', 'antra...@caret.cam.ac.uk', '
gopal.ramasammyc...@gmail.com', 'david.horw...@uct.ac.za', '
r...@media.berkeley.edu']) ← Mismatch
There were 54 lines in the file with From as the first word
The desired output result:
stephen.marqu...@uct.ac.za
lo...@media.berkeley.edu

Re: [Tutor] String Attribute
Hi Emile,
Question: What is the source of the line 7 syntax: mbox.split?
Here is a copy of the Traceback message:
NameError
Traceback (most recent call last)
C:\Users\vm\Desktop\apps\docs\Python\8_5_v_26.py in ()
5 addresses = set()
6 for addr in [ fromline.split()[0]
> 7 for fromline in mbox.split('From ')
8 if fromline ]:
9 count = count + 1
NameError: name 'mbox' is not defined
Revised code:
fname = raw_input("Enter file name: ")
if len(fname) < 1 : fname = "mbox-short.txt"
fh = open(fname)
count = 0
addresses = set()
for addr in [ fromline.split()[0]
for fromline in mbox.split('From ')
if fromline ]:
count = count + 1
print addr
print "There were", count, "lines in the file with From as the first word"

Re: [Tutor] String Attribute
Hi Everyone: Let me repost the question: You will parse the From line using split() and print out the second word in the line (i.e. the entire address of the person who sent the message). Then print out a count at the end. *Hint:* make sure not to include the lines that start with 'From:'. You can download the sample data at http://www.pythonlearn.com/code/mbox-short.txt Regards, Hal On Sat, Aug 1, 2015 at 9:18 AM, Emile van Sebille wrote: > Hi Hal, > > Seeing now that the output is only extracted from six address blocks, can > you paste in the full contents of the file mbox-short.txt?

Re: [Tutor] String Attribute
Hi Alan,
There is an indent message in the revised code.
Question: Where should I indent the code line for the loop?
View the revised codes with loop indents, below:
--->Revised Code v.2 wo/indent from lines 8-12:
fname = raw_input("Enter file name: ")
if len(fname) < 1 : fname = "mbox-short.txt"
fh = open(fname)
count = 0
addresses = set()
for line in fh:
if line.startswith('From'):
line2 = line.strip()
line3 = line2.split()
line4 = line3[1]
addresses.add(line)
count = count + 1
print "There were", count, "lines in the file with From as the first word"
print addresses
---> Message output reads:
In [62]: %run _8_5_v_25.py
File "C:\Users\vm\Desktop\apps\docs\Python\_8_5_v_25.py", line 8
line2 = line.strip()
^
IndentationError: expected an indented block
--->Revised Code v.3 w/indent from lines 8-12:
fname = raw_input("Enter file name: ")
if len(fname) < 1 : fname = "mbox-short.txt"
fh = open(fname)
count = 0
addresses = set()
for line in fh:
if line.startswith('From'):
line2 = line.strip()
line3 = line2.split()
line4 = line3[1]
addresses.add(line)
count = count + 1
print "There were", count, "lines in the file with From as the first word"
print addresses
