Hi Vigresh,

You can try Geopandas and Georasters which are specialized packages for GIS.

Best,

You can do the equivalent from gdal's Python interface, but it's a bit more involved. There's also a QGIS plugin to interactively build the GDAL command, if you'd like to interactively select the coregistration points.
