Good evening,

Efficiency is best addressed first and foremost, not by hardware,
If the file is big use Peter's method, but 45 minutes still seems
very long so it may be theres a hidden bug in there somehwew.

got some clue on this? Please advise.
You can use os.walk() to get a list of directories and files and
then just throw away the files...
x=0
y=0
w=raw_input("Input: ")
w=list(w)
for x in range(len(w)):
a=w[x]
t=0
print a

print "hi"

Thanks Alan, Peter and Steve,
Instead of answering each one of you independently let me try to use
my response to Steve's message as the basis for an answer to all of
you.

Use os.walk

This is a very inefficient approach because you repeat counting the number
of occurrences of a word that appears N times N times:

Hi,
I'm trying to do something that should be very simple. I want to
generate a list of the words that appear in a document according to
their frequencies. So, the list generated by the script should be
something like this:
the : 3
book: 2
was : 2
read: 1
by: 1
