iterating in a dictionary.. (double iteration) python
<p>I have a dictionary </p>

<pre><code>example: A = {1:'one',2:'two' , 3: 'three}
</code></pre>

<p>so what I want is basically like a 2 for loops sort of stuff..
so that I can get the following order..</p>

<pre><code># 1 2
# 1 3
# 2 3
... and so on if more elements are there
</code></pre>

<p>so basically that o(n2) operation.. where we have a loop withing a loop
how do we achieve this in python dictionary.
I am having a hard time figuring that out..</p>

<pre><code>for key in A.keys():
      # how do i Access all the other keys.. 
           # do something
</code></pre>

<p>Thanks</p>
