# we get our vectorized solution like so
# For df.columns = ['w', 'quat_x', 'quat_y', 'quat_z']

# If needed as a dataframe output

from scipy.spatial.transform import Rotation

quaternion_data = [x, y, z, w]
rot = Rotation.from_quat(quaternion_data)
rot_euler = rot.as_euler('xyz', degrees=True)
print(rot_euler)
