MRAB,

The Revised code produces a traceback:
()
      9
     10 c = [0 for i in range(24)]
---> 11 f  = open(filename,'r')
     12 for l in f:
     13      h = int(l.split()[X].split(':')[Y])

NameError: name 'filename' is not defined



The revised code reads:

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

c = [0 for i in range(24)]
f  = open(filename,'r')
for l in f:
     h = int(l.split()[X].split(':')[Y])
     c[h] = c[h] + 1
f.close()
for i in range(24):
     print '{:02d} {}'.format(i, c[i])


How do I define the file name in order to remove the traceback?

Regards,
Hal
