This is big enlightenment :) Thank you! :)

I found problem with eval() when it comes to pass quoted strings.
I circumvent that by encapsulating the strings in variable or tuple.
The principle is to have a name which will refers a function somewhere in the
program and to call that function, plus additional data passed in.

In other word I'd expect something:

function_list= ['add' ,'paint', 'read']
for func in function_list:
      func(*data)
I tried getattr, and I saw that result. I only investigate a little, so I
still have a small perplexity.
