title: Python version settings
body: <p>I work on Ubuntu with Wingware Python IDE. The version, which we use by our projects is <code>2.7.X</code></p>
  
  <p>This morning I updated the IDE, and it became a version <code>&gt;3.x.x</code></p>
  
  <p>Now I want to install the old version <code>2.7.3</code>, after I read TFM and try to define PYTHONPATH, I check my Python version on Ubuntu with the command:</p>
  
  <pre><code>python --version
  </code></pre>
  
  <p>and got the answer <code>2.7.3</code>. Now I can not understand, why I have version <code>3.x.x</code> in Wingware and <em>how exactly</em> (the import file is not clear) I can change my version after setting Python manually described <a href="https://wingware.com/doc/intro/tutorial-python-path" rel="nofollow">here</a> </p>
  
  <p>Actually: It depends on wingware, because I can execute <code>Python 2.7.3</code> in IPython and in console. </p>
  
  <p>EDIT: I solved this problem myself. Here's my solution: 
  Following the <a href="https://wingware.com/doc/intro/tutorial-python-path" rel="nofollow">manual</a>:</p>
  
  <ol>
  <li><p>Use <code>Python - Executable</code></p></li>
  <li><p>Use Interpreter to find right path (in my way it was <code>/usr/bin/python3.2</code>)</p></li>
  <li><p>Go in <code>/usr/bin/</code></p></li>
  <li><p>Select right Python version. This path has ALL Python versions, you should just select the right one</p></li>
  </ol>
