In that case, you want to sort the entire collection, not a single
key-value pair.
It seems to me you can do this fairly efficiently with collections.Counter.
import collections
with open(raw_input("Enter file name: ")) as f:
counts = collections.Counter(line.split()[5].rstrip() for line in
f if line.startswith("From "))
counts = counts.items()
counts.sort()
for hour, count in counts:
print hour, count
The most important part is getting items() and then sorting the whole thing.
