<p class="has-pale-cyan-blue-background-color has-background">Python’s <strong><code>return</code> keyword</strong> commands the execution flow to <strong>exit a function immediately</strong> and return a value to the caller of the function. You can specify an <strong><em>optional return value</em></strong>—or even a return expression—<strong><em>after </em></strong>the <code>return</code> keyword. If you don’t provide a return value, Python will return the default value <code>None</code> to the caller.</p>

<h2>Return Keyword Followed by Return Value</h2>
<p>Here’s an example of the return keyword in combination with a return value:</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="">def f(): return 4 print(f())
# OUTPUT: 4</pre>
<p>Within function <code>f()</code>, Python returns the result 4 to the caller. The <code><a href="https://blog.finxter.com/the-separator-and-end-arguments-of-the-python-print-function/" title="Python Print Function [And Its SECRET Separator & End Arguments]" target="_blank" rel="noreferrer noopener">print()</a></code> function then prints the output to the shell. </p>
</p>
<h2>Return Keyword Followed by Return Expression</h2>
<p>Here’s an example of the return keyword in combination with a return expression:</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="">def f(): return 2+2 print(f())
# OUTPUT: 4</pre>
<p>Within function <code>f()</code>, Python evaluates the expression <code>2+2=4</code> and returns the result 4 to the caller. The <code><a href="https://blog.finxter.com/the-separator-and-end-arguments-of-the-python-print-function/" target="_blank" rel="noreferrer noopener">print()</a></code> function then prints the output to the shell.</p>
<h2>Return Keyword Followed by No Value</h2>
<p>Here’s an example of the return keyword without defining a return value:</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="">def f(): return print(f())
# OUTPUT: None</pre>
<p>Within function <code>f()</code>, Python returns the default value <code>None</code> to the caller. The <code><a href="https://blog.finxter.com/the-separator-and-end-arguments-of-the-python-print-function/" target="_blank" rel="noreferrer noopener">print()</a></code> function then prints the output to the shell.</p>
