title: How to check if pyodbc is already installed on my MacOS?
body: <p>Is there any way to check if pyodbc is already installed in my MacOS (10.9)? I already had python 2.7 installed on my mac and in addition I installed python3 later. Now both version of the python works fine from my terminal.</p>
  
  <p>I heard pyodbc will not work alone and it  needs a odbc manager (and the recommended is iodbc for mac), is there any  way for that to check as well? Me kind of new to these things and so do not intend to create mess by installing another pyodbc or iodbc which is already there on my mac. </p>
  
  <p>Not sure if this info is relevant, but i want to create a database connection using ODBC that has to work both for MySQL and Postgres (I have them both installed on my mac), select some info from a table and close the connection. And right now I am on my first phase of creating a connection..</p>
  
  <p>Helps will be highly appreciated.  </p>
