Is this a Dictionary in an older Python version?
<p>I'm new to Python and am reading a book that came out in 2009 and so uses Python 2.5 syntax. It does the following:</p>

<pre><code>_fields_ = [
    ("cb", DWORD),
    ("lpReserved", LPTSTR),
    ...
]
</code></pre>

<p>To me it looks like a list of tuples, but at the same time it feels like a Map/Dictionary. Was this the older syntax?</p>
