title: Import functions from one python file to another
body: <p>Say i have a python file called <code>a.py</code> with the functions x,y,z.</p>
  
  <p>I want to import them to a new file called <code>b.py</code> </p>
  
  <p>I tried: <code>from a import *</code>   AND   <code>from a import all</code> with no luck.</p>
  
  <p>I can just do it separately: <code>from a import x</code> , <code>from a import y</code> ....</p>
  
  <p>How can i import them ALL at once?</p>
