Grok learning python programming
<p>I am wondering how to solve this problem:</p>

<p>You are curious about the most popular and least popular colours of cars and decide to write a program to calculate the frequency of car colours.</p>

<p>Your program should read in the colour of each car until a blank line is entered, and then print out (in any order) all the different colours of car with counts.</p>

<p>For example:</p>

<pre><code>Car: red
Car: white
Car: blue
Car: green
Car: white
Car: silver
Car: 
Cars that are green: 1
Cars that are silver: 1
Cars that are red: 1
Cars that are white: 2
Cars that are blue: 1
</code></pre>

<p>â
Here is another example:</p>

<pre><code>Car: red
Car: white
Car: white
Car: red
Car: white
Car: white
Car: white
Car: 
Cars that are red: 2
Cars that are white: 5
</code></pre>

<p>You have to call <code>input</code> multiple times with a sentinel value, then count the objects, then iterate over the keys and values, and then print a formatted string for each count. Reasonably straightforward with one line of code:</p>

<pre><code>print(*('Cars that are {}: {}'.format(*item) for item in __import__('collections').Counter(iter(lambda: input('Car: '), '')).items()), sep='\n')
</code></pre>
