This question, though specific in nature, can be abstracted to a general question about Python.
Imagine there is a function that takes in a few parameters. This list of parameters is of variable length; however, the types of the given parameters are not variable. The parameters come in groups of three, and the first and second are lists of floats and the third is a string. Then it repeats. So, in a way, the parameters are not of variable length, it's restricted to multiples of 3.
The types can be anything, those are just the ones specific to my problem. I have a matplotlib plot function that looks like this in the docs:
a.plot(x1, y1, 'g^', x2, y2, 'g-',...)
As you can see, number of groups of three can be however long you want.
I have a list of lists that contains all of my x values (x1, x2, x3, ...) and a list of lists that contain all of my y values (y1, y2, y3,...). Not knowing how long those lists are (they are always equal in length to each other, though), and assuming I can have some dictionary that maps certain indexes to certain strings (for the string parameter), how can I pass indexes from variables length list of lists to this function.
Ideally, I guess it would look something like this is pseudo-code:
for element in list_of_lists:
myFunction(lists_of_lists[element])
Except that this code would just execute the myFunction for all the elements in the list_of_lists. Instead, I want one long list of parameters and only execute the function once. I also feel like this problem is interested for Python as a whole, not just my specific issue. Thanks in advance!
