You just need to use the full path to the file - for example;
</div><div><br></div><div>open('/path/to/file/p.txt')</div><div><br></div><div>If your on windows that will likely that with c:// etc.</div><div><br></div>

Perhaps check your indentation, the code under the 'if' does not look indented correctly on my phone. Also, assumption is that the p.txt file has some content where lines start with TRAN and the file/directory permissions are correct.<br>
<br>
I tried the code and works fine for me<br>
