Thank you, Christian. This solution was one I was not expecting and am
glad to receive it. It is one I will explore in greater detail later.

Hi,
Given a list of options: option_1.......option_n. For each option I have
a corresponding function: func_1..... func_n. I have all function names
defined in a list similar to flist = [func_1, func_2,.......func_n]
which I know is a legitimate construct having found a similar construct
discussed by Kent Johnson in 2005.
What I do not know how to do is to call the selected function. If the
index of options is 1, then I want to call func_2; do I code
flist[index]? I do not think Python has a branch indirect construct so I
cannot use anything similar to that methodology. What is the best
approach to take to solve this problem?
Thank you for any assistance, hints, solutions, and guidelines.
Robert

Why not use a dictionary to do the heavy lifting for you
>>> import string
>>> funcs = {1:string.upper, 2:string.lower}
>>> funcs[1]('this is a simple test')
'THIS IS A SIMPLE TEST'
>>> funcs[2]('THIS IS A SIMPLE TEST')
'this is a simple test'
(Your top-posting makes the thread hard to follow)
Note that once it's a dictionary, you can use whatever keys you would
normally use in a dictionary. For example, if the options are strings,
use a string as the key. If they literally are numbers, then a list is
preferable, but a dictionary gives you other choices.
