Hi experts!

I have the Numpy arrays AAA=[a1,a2,...] and BBB=[b1,b2,...]. I know that I can export these arrays doing:

np.savetxt('array AAA.csv', AAA, delimiter=',') 
np.savetxt('array BBB.csv', BBB, delimiter=',')

I wanna export one csv file that include both arrays + labels, in this way:

AAA | BBB
----------
a1  | b1
a2  | b2
.   |  . 
.   |  . 
.   |  .

How can I do that?

Waiting for your answers.

Thanks a lot.

Best regards

Do you mean a csv file? In that case, perhaps taking a look at the `csv` module documentation might be helpful. The [third](https://docs.python.org/2/library/csv.html#examples) example there that might be useful for your purposes. It might help to send as input to the `writerows` method the `zip` of `AAA` and `BBB` from your example.

You can do:

sage: C = zip(A, B)
sage: with open('file_path.csv', 'w') as f:
....:     c = csv.writer(f)
....:     c.writerows(C)
