How to make several plots on a single page using matplotlib?

I have written code that opens 16 figures at once. Currently, they all open as separate graphs. I’d like them to open all on the same page. Not the same graph. I want 16 separate graphs on a single page/window. Furthermore, for some reason, the format of the numbins and defaultreallimits doesn’t hold past figure 1. Do I need to use the subplot command? I don’t understand why I would have to but can’t figure out what else I would do?
