Arrays & Text-files

Question

So I have that function that outputs an array. I'd like to ask how do I save said function on a text-file for then calling that array back to further iterate it and save it back again. And the cycle goes on.

Answer 1

So when you say "save said function" you mean you want to save the array which is the result of the function right ?
If you're just interested in the result (so you want a simple solution that works for numbers, very well by the way) you can use the library numpy (a must know for data scientists using Python) :
https://docs.scipy.org/doc/numpy-1.14.5/reference/generated/numpy.save.html

If you're interested in creating your own function, it would involve opening, reading and writing in files. It would mean creating your custom made "tokenizer". A very good exercise imo.
If that's what you're looking for, I would be glad to help

Answer 2

If all you want to do is saving some data to a text file, you don't need numpy or even some import from the standard library.

The link down there leads to a description of basic read and write functions.

Answer 3

Thank you dhm, what I wanted to do seems like a tokenizer.
