Denis,

What are the values of X & Y from the code as follows:

Code reads:
handle = """From stephen.marquard at uct.ac.za Sat Jan  5 09:14:16 2008
>From louis at 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: ")# insert # to add snippet file data
#handle = open (fname, 'r')# insert # to add snippet file data

for line in handle:
    if line.startswith("From "):
        time = line.split() # splitting the lines ->
        # print time: ['From', 'stephen.marquard at uct.ac.za', 'Sat',
'Jan', '5', '09:14:16', '2008']
        for hours in time: #getting the index pos of time ->

            hours = line.split(":")[2] # splitting on ":" ->
        line = line.rstrip()

        count[hours] = count.get(hours, 0) + 1 # getting the index pos of hours.

lst = [(val,key) for key,val in count.items()] # find the most common words
lst.sort(reverse=True)

for key, val in lst[:12] :
     print key, val
