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.
maxval = none
maxkee = none
for kee, val in count.items():
if maxval == none or maxval <val:
maxval = val
maxkee = kee
print items
Question: What is the cause of the dictionary line message?
Regards,
Hal.
