Splitting by ',' in a dictionary while retaining the lists inside : <p>I've been looking for a way to split by ',' in a dictionary while retaining the present lists but have not been succesful. I want to split this dictionary:</p>

<pre><code>{'R_ARABR': ['YHR104W'], 'R_GLYCt': ['YLL043W'], 'R_LPP_SC': ['YDR284C', 'YDR503C'], 'R_TREH': ['YDR001C', 'YBR001C'], 'R_CTPS2': ['YBL039C', 'YJR103W'], 'R_CTPS1': ['YBL039C', 'YJR103W']}
</code></pre>

<p>To appear like this:</p>

<pre><code>{'R_ARABR': ['YHR104W'],
'R_GLYCt': ['YLL043W'],
'R_LPP_SC': ['YDR284C', 'YDR503C'],
'R_TREH': ['YDR001C', 'YBR001C'],
'R_CTPS2': ['YBL039C', 'YJR103W'],
'R_CTPS1': ['YBL039C', 'YJR103W']}
</code></pre>

<p>Help is much appreciated!</p>
