How do I install Python 3.7 in google cloud shell : <p>I have python 3.5 on my google cloud shell and want 3.7 so I can do command line debugging of code I am going to deploy via google cloud functions (and use 3.7 features such as f-strings).</p>

<p>I try various forms of the following:</p>

<pre><code>sudo apt-get install python37
</code></pre>

<p>and always get back</p>

<pre><code>Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package python37
</code></pre>

<p>Any help would be really appreciated!</p>
