title: Python importing
body: <p>I have a file, <code>myfile.py</code>, which imports <code>Class1</code> from <code>file.py</code> and <code>file.py</code> contains imports to different classes in <code>file2.py</code>, <code>file3.py</code>, <code>file4.py</code>.</p>
  
  <p>In my <code>myfile.py</code>, can I access these classes or do I need to again import file2.py, file3.py, etc.?</p>
  
  <p>Does Python automatically add all the imports included in the file I imported, and can I use them automatically?</p>
