    text
    copied!<p>In Python, I really enjoy how concise an implementation can be when using list comprehension. I love to do concise list comprehensions this:</p> <pre><code>myList = [1, 5, 11, 20, 30, 35] #input data bigNumbers = [x for x in myList if x &gt; 10] </code></pre> <p>However, I often encounter more verbose implementations like this:</p> <pre><code>myList = [1, 5, 11, 20, 30, 35] #input data bigNumbers = [] for i in xrange(0, len(myList)): if myList[i] &gt; 10: bigNumbers.append(myList[i]) </code></pre> <p>When a <code>for loop</code> only looks through one data structure (e.g. <code>myList[]</code>), there is usually a straightforward list comprehension statement that is equivalent to the loop. <br> <strong>With this in mind, is there a refactoring tool that converts verbose Python loops into concise list comprehension statements?</strong></p> <hr> <p><a href="https://stackoverflow.com/questions/2532525/how-do-i-make-this-simple-list-comprehension?rq=1">Previous</a> <a href="https://stackoverflow.com/questions/10637037/replacing-while-loop-with-list-comprehension">StackOverflow</a> <a href="https://stackoverflow.com/questions/2532525/how-do-i-make-this-simple-list-comprehension?rq=1">questions</a> have asked for advice on transforming loops into list comprehension. But, I have yet to find a question about <strong>automatically</strong> converting loops into list comprehension expressions.</p> <hr> <p><strong>Motivation:</strong> There are numerous ways to answer the question "what does it mean for code to be clean?" Personally, I find that making code concise and getting rid of some of the fluff tends to make code cleaner and more readable. Naturally there's a line in the sand between "concise code" and "incomprehensible one-liners." Still, I often find it satisfying to write and work with concise code.</p>
