How could I get right tile (WGS 84 / Lat-lon / Geographic / EPSG:4326) by long, lat and zoom?

I’m trying to get tile by long, lat and zoom by formula:

row = int((90 - lat) / 180 * 2 ** zoom)
col = int((180 + lon) / 180 * 2 ** zoom)

but it doesn’t work. Here is related question https://gis.stackexchange.com/questions/239496/how-to-convert-long-lat-to-a-tile-of-nasa-gibs-wgs-84-lat-lon-geographic

For GIBS GCS, the level 0 resolution is 288 deg / tile, not 180 deg/tile. It was chosen to approximate the full resolution of the MODIS images, avoiding oversampling or undersampling, while still having full width tiles at most levels (2 and up).

Making this adjustment, the formula to use is:

row = ((90 - lat) * (2 ** level)) // 288
col = ((180 + lon) * (2 ** level)) // 288

Web Mercator assumes the world map fits in a square tile of 256x256, then keeps subdividing. There is also a GCS grid where the whole world fits in two tiles side by side at top level, the way your original formula works. There are no partial content tiles ever. Those are the most common tiling schemes.

You might want to look at GDAL, it has python bindings and knows how to fetch the data from GIBS, using the GDAL WMS, hiding the tiling aspect.
