How to use `numpy.savez` in a loop for save more than one array?

Question

From a loop I\'m getting an array. I want to save this arrays in a tempfile. The problem is that np.savez only saves the last array from the loop.

Answer 1

You can use the *args arguments to save many arrays in only one temp file.

np.savez(tmp, *getarray[:10])

or:

np.savez(tmp, *[getarray[0], getarray[1], getarray[8]])
