I'm parsing a simple file and given a line's keyword, would like to call
the equivalently named function.
There are 3 ways I can think to do this (other than a long if/elif
construct):
1. eval()
2. Convert my functions to methods and use getattr( myClass, "method" )
3. Place all my functions in dictionary and lookup the function to be
called
Any suggestions on the "best" way to do this?
Thank you,

You are on the right track with (2), but you need not do any conversion.
All objects that have attributes (and a function is an attribute) can
be looked up with getattr.
For instance, from a module (function getcwd from modules os):
>>> import os
>>> getattr(os,'getcwd')
<built-in function getcwd>
>>> getattr(os,'getcwd')()
'/home/gherron'
You can use getattr with objects, classes, modules, and probably more.
