Efficiency of imports in Python
<p>I have a module with many functions:</p>

<p><strong>Module One</strong></p>

<pre><code>def a():
 ...
def b():
 ...
def c():
 ....
</code></pre>

<p>Now, from a different module, I need to import only function b. For that purpose, i am using the syntax:</p>

<pre><code>from One import b
</code></pre>

<p><strong>My question</strong> - beside from namespace considerations, is there any positive effect on the time complexity of my program if I use the import stated above rather than <code>import One</code> , since that way I only import the necessary functions (for the sake of the example I only used 3 function in <code>module One</code>, but I have many more)</p>
