python - how to identify cross streets for points that are not at intersections?

I have points that fall in the middle of city streets (so not at an intersection). I would like to automate (ideally, with python) a way to identify the cross streets that these points are between. For example, in the screenshot, the point falls on West 231 Street. I would like to find a way to automate a result that returns Palisade Avenue and Independence Avenue. My points file has columns for these cross streets, with the ultimate goal of placing those selected values there.
