A global variables list (GVL) is used to declare global variables. If a GVL is placed in the Global node of the Software catalog > Variables > Global Variables or the Applications tree, the variables will be available for the entire project.
A global list can be declared in python by first specifying a function to do and then explicitly specifying the variables to be global within that function.
We declare a variable global by using the keyword global before a variable. All variables have the scope of the block, where they are declared and defined in. They can only be used after the point of their declaration.
Or use globlist[:] = list and drop the global keyword.
I am using a list on which some functions works in my program. This is a shared list actually and all of my functions can edit it. Is it really necessary to define it as "global" in all the functions?
I mean putting the global keyword behind it in each function that uses it, or defining it outside of all the functions is enough without using the global word behind its definition?
