Earlier, you learn how to use output.

If you have pandoc you can export pandas df to excel or csv by

df.to_excel("rumm_anla.xl ")
df.to_csv('ch06/out.csv')

You can then Read the data to your df

Numpy has its own data save format.

np.save('aik', np.array([[1, 2, 3], [4, 5, 6]]))
np.load('aik.npy')

If you have text, you will need to allow pickle

y = np.load('aik.npy',allow_pickle=True)

It will create a file with the npy extension. Best to save it to a temp folder.
