title: How to delete extra pythons on Mac OS X Sierra
body: <p>In the usr/bin folder, there are three versions of Pythons installed:  Python, Python2.6, Python2.7 (the folder names) - not sure what version is for Python folder.</p>
  
  <p>My issue, originally, was that I tried to install the module 'pandas' to run a script, python keeps telling me pandas could not be found.</p>
  
  <p>'pip freeze' shows me pandas is already installed.
  However, I could not find pandas using python>>help>>modules. </p>
  
  <p>So I suspected there are multiple pythons installed causing pip installing for one of them, but the default python is a different one.</p>
  
  <p>So my questions are - 
  1 Which python is the default one that comes with macOS Sierra? (I can confirm pandas currently is installed for Python, not Python2.6 or Python2.7)
  2 Can I remove extra Pythons that do not have pandas? 
  3 How can I find what it the default Python when I type 'Python...' and how to install pandas for that python?</p>
  
  <p>Solved:
  Thanks for the comments and reply.
  I used "python2.7 install pip" to install pip for python2.7. Then I used command 'pip2.7 install pandas'. This way, pandas is installed for the default python. (The command 'pip install pandas' on my machine, is installing for python 2.6.)</p>
