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?
(3) is the securest way since the input file cannot induce unexpected
behaviour.
With this respect (1) is a folly and (2) is a good compromise since you
still can write a condition before passing "method" to getattr(). Btw,
if you look into the guts, you'll realize that (2) is nearly the same as
(3)...
