zed shaw's exercise 15 open function
<p>I am a little stuck with zed shaw's exercise 15.
Actually I had no problem with the original program,
but the problem is when I try out the extra credit
where he asks us to use raw input instead of argv.</p>

<p>so, this is the code I used</p>

<pre><code>filename=raw_input("enter filename :")
print "here's your file %r" % filename
txt=open(filename)
print txt.read()
</code></pre>

<p>when it asks for filename, I give the path e:\python\ex15_sample.txt
I am getting the following error in
this line --> txt = open(filename)
and it further says
no such file or directory</p>

<p>So, what do I do?</p>
