title: Does Multiple Imports in Python effect memory?
body: <p>Let's say I have a python script</p>
  <pre><code>import pandas as pd
  import matplotlib
  import seaborn
  </code></pre>
  <p>Now  As I have read that pandas has built-in plotting which is on matplotlib, similarly Seaborn is built on top of matplotlib, So When I import all these 3, does this have any issue on performance/memory as single package is imported multiple time, or is there anyway to improve it.</p>
