title: Installing package in Python
body: <p>I have in my laptop installed both python 2.7 and python 3.5 . When I install a package and use for example:</p>
  
  <pre><code>pip install thunder-python
  </code></pre>
  
  <p>or </p>
  
  <pre><code>easy_install thunder
  </code></pre>
  
  <p>in command prompt the packages are installed for python 3.5. How can I install the packages in order to use them in python 2.7? I am using Windows 10.</p>
