image = Image.open(filepath)
data_exif = image._getexif()
image.close()
data = {ExifTags.TAGS.get(k): v for k, v in data_exif.items()}
if 'GPSInfo' in data and isinstance(data['GPSInfo'], dict):
    data['GPSInfo'] = {ExifTags.GPSTAGS.get(k): v for k, v in data['GPSInfo'].items()}
pprint.pprint(data)
