I have an unknown number of functions in my python script (well, it is known, but not constant) that start with site_... I was wondering if there's a way to go through all of these functions in some main function that calls for them. something like: foreach function_that_has_site_ as coolfunc if coolfunc(blabla,yada) == true: return coolfunc(blabla,yada) so it would go through them all until it gets something that's true. thanks!Read the article

Good practice of using list of function in Python
- by riskio
I am pretty new to python and I discovered by myself that I can create a list of function and call with a for loop. example: def a(args): print "A" def b(args): print "B" def c(args): print "C " + str(args) functions = [a,b,c] for i in functions: i(1) So, my question is: is there any good practice or elegant way to use list of functions and what is a good use of all this? (do have a particular name the "list of functions"?) thank youRead the article
