Parsing Tabbed Numbers on a Line
<p>I have a text file with a bunch of lines of series of numbers, resembling this format: </p>

<pre><code>1   80,982  163,8164    170,2620    145,648 200,8021    173,2069    92,647  26,4122 140,546 11,1913 160,6461    27,7905 40,9047 150,2183    61,9146 159,7420    198,1724    114,508 104,6647    30,4612 99,2367 138,7896    169,8700    49,2437 125,2909    117,2597    55,6399 
</code></pre>

<p>I'd like to create a nested dictionary that maps the first number in the sets of two numbers to the second, and have all of that mapped to the line number. So for the first few entries in this example (line 1), it would look like this:</p>

<pre><code>{1: {80: 982}, {163: 8164}, {170: 2620}} 
</code></pre>

<p>I'm not sure how to achieve this with my limited text parsing  abilities. Would I use the split method using tabs and commas as delimiters? </p>
