title: Why does my Python petl library appear to be missing functions?
body: <p>I'm new to Python (not new to programming) and am trying to learn both the Python language and the Petl library for some ETL work I need to do. </p>
  
  <p>I'm going through some basic tutorials on petl.readthedocs.org and have come across a couple missing functions and am wondering what I'm doing wrong... Below is a screenshot of an example where the function 'fromcolumns' isn't recognized even though its featured in petl tutorials. </p>
