<p>Say your file is stored in file ‘code.py’. Now, you can open the file, read all lines, get rid of leading and trailing whitespace characters, and store the result in a Python list in a single line of code. Here’s the code:</p>
<pre class="EnlighterJSRAW" data-enlighter-language="generic" data-enlighter-theme="" data-enlighter-highlight="" data-enlighter-linenumbers="" data-enlighter-lineoffset="" data-enlighter-title="" data-enlighter-group="">print([line.strip() for line in open("code.py")])</pre>
<p>Python is beautiful! <img src="https://s.w.org/images/core/emoji/12.0.0-1/72x72/1f60d.png" alt="?" class="wp-smiley" style="height: 1em; max-height: 1em;" /></p>

<p><strong>OFFICIAL BOOK DESCRIPTION:</strong> <em>Python One-Liners will show readers how to perform useful tasks with one line of Python code. Following a brief Python refresher, the book covers essential advanced topics like slicing, list comprehension, broadcasting, lambda functions, algorithms, regular expressions, neural networks, logistic regression and more. Each of the 50 book sections introduces a problem to solve, walks the reader through the skills necessary to solve that problem, then provides a concise one-liner Python solution with a detailed explanation.</em></p>
