Is there any other purpose of "dictionary.get" function in Python with two elements in it, apart from checking for a variable in the list? : <p>I thougt it could store the answer for the case when user inputs a wrong key in it, like this:</p>

<pre><code>month_conversion.get("Git", "Not a valid key")
month_conversion = input()
</code></pre>

<p>So, if user input "Git" it would print out "Not a valid key"
But it doesn't store it and just prints out "None"</p>
