I’m analyzing some Python code and I don’t know what
pop = population[:]
means. Is it something like array lists in Java or like a bi-dimensional array?

It is an example of slice notation, and what it does depends on the type of
population. Ifpopulationis a list, this line will create a shallow copy of the list. For an object of typetupleor astr, it will do nothing (the line will do the same without[:]), and for a (say) NumPy array, it will create a new view to the same data.
