Strings variations in python - what do they mean?
<p>This is a complete noob question....</p>

<p>but why do some strings in python appear as: </p>

<pre><code>{u'foobar: u'bar}
</code></pre>

<p>while others appear as:</p>

<pre><code>{foobar: bar}
</code></pre>

<p>are they equivalent? How do you convert between the two?</p>
