How to Filter a List of Lists in Python?
<div><p><strong>Short answer: To filter a list of lists for a condition on the inner lists, use the list comprehension statement <code>[x for x in list if condition(x)]</code> and replace <code>condition(x)</code> with your filtering condition that returns <code>True</code> to include inner list <code>x</code>, and <code>False</code> otherwise. </strong></p>

<p>Lists belong to the most important data structures in Python—every master coder knows them by heart! Surprisingly, even intermediate coders don’t know the best way to <a href="https://blog.finxter.com/how-to-filter-a-list-in-python/" target="_blank" rel="noreferrer noopener">filter a list</a>—let alone a list of lists in Python. This tutorial shows you how to do the latter!</p>
<p><strong>Problem</strong>: Say, you’ve got a list of lists. You want to filter the list of lists so that only those inner lists remain that satisfy a certain condition. The condition is a function of the inner list—such as the average or sum of the inner list elements.</p>

<figure class="aligncenter size-large is-resized"><img src="https://blog.finxter.com/wp-content/uploads/2020/05/filter-1024x576.jpg" alt="" class="wp-image-8362" width="768" height="432" srcset="https://blog.finxter.com/wp-content/uploads/2020/05/filter-scaled.jpg 1024w, https://blog.finxter.com/wp-content/uplo...00x169.jpg 300w, https://blog.finxter.com/wp-content/uplo...68x432.jpg 768w" sizes="(max-width: 768px) 100vw, 768px" /></figure>
</div>
<p><strong>Example</strong>: Given the following list of lists with weekly temperature measurements per week—and one inner list per week.</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=""># Measurements of a temperature sensor (7 per week)
temperature = [[10, 8, 9, 12, 13, 7, 8], # week 1 [9, 9, 5, 6, 6, 9, 11], # week 2 [10, 8, 8, 5, 6, 3, 1]] # week 3</pre>
<p>How to filter out the colder weeks with average temperature value <8? This is the output you desire:</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(cold_weeks)
# [[9, 9, 5, 6, 6, 9, 11], [10, 8, 8, 5, 6, 3, 1]]</pre>
<p>There are two semantically equivalent methods to achieve this: <a rel="noreferrer noopener" href="https://blog.finxter.com/list-comprehension/" target="_blank">list comprehension</a> and the <a rel="noreferrer noopener" href="https://blog.finxter.com/how-to-get-rid-of-pythons-map-function-with-list-comprehension/" target="_blank"><code>map()</code> function</a>. Let’s explore both variants next.</p>
<p>If you’re short on time, you can also get a quick overview by playing with the code in your web browser—I’ll explain the code after that.</p>

<h2>Method 1: List Comprehension</h2>
<p>The most Pythonic way of filtering a list—in my opinion—is the list comprehension statement <code>[x for x in list if condition]</code>. You can replace <code>condition</code> with any function of <code>x</code> you would like to use as a filtering condition. Only elements that are in the <code>list</code> <strong>and </strong>meet the <code>condition</code> are included in the newly created list.</p>
<p><strong>Solution</strong>: Here’s how you can solve the above problem to filter a list of lists based on a function of the inner lists:</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=""># Measurements of a temperature sensor (7 per week)
temperature = [[10, 8, 9, 12, 13, 7, 8], # week 1 [9, 9, 5, 6, 6, 9, 11], # week 2 [10, 8, 8, 5, 6, 3, 1]] # week 3 # How to filter weeks with average temperature <8? # Method 1: List Comprehension
cold_weeks = [x for x in temperature if sum(x)/len(x)<8]
print(cold_weeks)
# [[9, 9, 5, 6, 6, 9, 11], [10, 8, 8, 5, 6, 3, 1]]</pre>
<p>The second and third list in the <a rel="noreferrer noopener" href="https://blog.finxter.com/how-to-sum-list-of-lists-in-python-rows/" target="_blank">list of lists</a> meet the condition of having an average temperature of less than 8 degrees. So those are included in the variable <code>cold_weeks</code>. </p>

<h2>Method 2: Filter() Function</h2>
<p>The <code>filter(function, iterable)</code> function takes a function as input that takes on argument (a list element) and returns a Boolean value that indicates whether this list element should pass the filter. All elements that pass the filter are returned as a new <code>iterable</code> object (a filter object).</p>
<p>You can use the <code>lambda</code> function statement to create the function right where you pass it as an argument. The syntax of the lambda function is <code>lambda x: expression</code> and it means that you use <code>x</code> as an input argument and you return expression as a result (that can or cannot use <code>x</code> to decide about the return value).
