I am trying to collect strings denoting the equipment allotted to an RPG character, classified as weapons, clothing, misc. goods, etc., and annotated as ‘W’, ‘C’, ‘G’, etc., and I am having trouble using eval() to set up empty lists: listW, listC, listG, and so on.

num = 5
print(eval(num*(num+1)/2))
why is it is showing an error.

I’d like to define some contextual functions that can then be used later, as per the example below.
