# 10.2 Write a program to read through the mbox-short.txt and figure out the distribution by hour of the day for each of the messages. You can pull the hour out from the 'From ' line by finding the time and then splitting the string a second time using a colon.
#From stephen.marquard@uct.ac.za Sat Jan  5 09:14:16 2008
# Once you have accumulated the counts for each hour, print out the counts, sorted by hour as shown below.

name = input("Enter file:")
if len(name) < 1:
    name = "mbox-short.txt"
handle = open(name)

counts = dict()

for line in handle:
    if line.startswith("From "):
        time = line.split()[5].split(":")
        counts[time[0]] = counts.get(time[0], 0) + 1

list=list()

for key, value in counts.items():
    list.append((key,value))
list.sort()

for hour, counts in list:
    print(hour, counts)

why is my code not working:
xs=open('8.5not.txt')
c=dict()
p=list()
for line in xs:
if line.startswith('From '):
words=line.split()
else:
continue
for word in words:
m=word[5].split(':')
c[m[0]]=c.get(m[0],0)+1
for k,v in c.items():
p.append(k,v)
p.sort()
print(p)

The code works but it is still problematic. If you write "From" instead of "From " without a space at the end, code blows up as it also iterates the lines whose length are smaller than 5.
