Hi Johannes,
Do you mean something like this:
if s in list:
eval(s)

Have a function with the same name as your list entry and perform an 
eval(string_name)

Hi,

I'm trying to be clear about this question, but maybe this can't be done. 

 

Let's say that you have a list that contains twenty strings. 

Your program reads in a string from a file.

The string from the file matches one of the strings in your list.

You want to perform a function that may be associated with that string.

You don't want to write twenty if statements to see if the string in the file 
matches and perform the function associated with that string.

You want to somehow get the program to see the string and the function 
associated with it and just perform it.

 

Is this possible?

 

Thanks.

 

Jim
