    <p>I understand what you're asking now I think. If you want to execute something in a file from the shell, the easiest way is to encapsulate it in a Class.</p> <p>Try changing your code to the following:</p> <pre><code>#!/usr/bin/python class Hello: def __init__(self): print "Hello, Interactive Shell World!" raw_input() </code></pre> <p>This makes a class called Hello where the constructor function runs the code you have in your current file. Then, start an interactive shell started in the same directory as the hello.py file. Here is a paste from an example session:</p> <pre><code>&gt;&gt;&gt; from hello import Hello &gt;&gt;&gt; Hello() Hello, Interactive Shell World! &lt;hello.Hello instance at 0xb782686c&gt; &gt;&gt;&gt; </code></pre> <p>It prints the message, waits for input, then prints the string representation of the newly created object and returns to the prompt. If you want to avoid the last printout just assign the object to a variable like:</p> <pre><code>&gt;&gt;&gt; h = Hello() </code></pre> <p>If you want to keep the ability to execute the file from the command line (rather than the shell) add this code to the bottom of the file:</p> <pre><code>if __name__ == '__main__': Hello() </code></pre> <p>You do "chmod +x" from the terminal. In the directory of the hello.py, run:</p> <p>chmod +x hello.py</p> <p>This gives you the ability to run your file like ./hello.py instead of "python hello.py". Now that I think of it, it sounds like you may be confusing the python interactive shell which a unix shell. You can run your file easily using "python hello.py" from a unix shell, but to run code from the python interactive shell, you will want to do something like I did above.</p>

    1. COI opened eclipse (not in sudo mode), i configured it with "auto config", then I copied that code, but when I try to execute it again i get : ImportError: No module named hello. I tried with import hello , and: from hello import Hello but i get the same result. any idea?

    2. COThat means the file hello.py is not on the python path. The easiest way to get it on the python path is to make sure you launch the interactive python shell in the same directory as hello.py, since the current directory should always be on the python path.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
