How to convert latitude and longitude to x and y with a certain limit on x and y resolution?

Question

Python

Let's say we have a list:

a = ['()', '()', '()', '()', '()', '()', '()', '()', '()', '()', '()', '()']
b = ['()', '()', '()', '()', '()', '()', '()', '()', '()', '()', '()', '()']
c = ['()', '()', '()', '()', '()', '()', '()', '()', '()', '()', '()', '()']
d = ['()', '()', '()', '()', '()', '()', '()', '()', '()', '()', '()', '()']
e = ['()', '()', '()', '()', '()', '()', '()', '()', '()', '()', '()', '()']
coordinates = [a, b, c, d, e]

Imagine that this is a conditional map of the world, I want to select the desired list item by geographical coordinates.
That is, I want to convert latitude and longitude to XY, where x = list item (the width of the list obtained from the coordinates list by y - height).
That is, such a "matrix" with a height of 5 and a width of 12 (these are restrictions)

Answer 1

Mercator projection + integer division

Answer 2

What's the problem with dividing 360 by 12 and 180 by 5 and filling out your lists.
