title: frame type in python
body: <p>In a <code>python reference manual</code> said that</p>
  
  <blockquote>
    <p>A code block is executed in an execution frame. A frame contains some
    administrative information (used for debugging) and determines where
    and how execution continues after the code block’s execution has
    completed.</p>
  </blockquote>
  
  <p>and</p>
  
  <blockquote>
    <p>Frame objects represent execution frames. They may occur
    in traceback objects</p>
  </blockquote>
  
  <p>But I don't understanf how frame does work. How can I get an acces to a current frame object? When is frame object creating? Is the frame object created everytime when a code of new block is strarting to execute?</p>
