Example: gdal reproject and resample python

#source
src = gdal.Open(src_filename, gdalconst.GA_ReadOnly)

#raster to match

match_proj = match_ds.GetProjection()
match_geotrans = match_ds.GetGeoTransform()
wide = match_ds.RasterXSize

#output/destination
dst = gdal.GetDriverByName('Gtiff').Create(dst_filename, wide, high, 1, gdalconst.GDT_Float32)
dst.SetGeoTransform(match_geotrans)

#run
gdal.ReprojectImage(src, dst, src_proj, match_proj, gdalconst.GRA_NearestNeighbour)
