How do you best store list data (between stopping and restarting notebook sessions) when there's too much for the notebook to handle as repr() output (when re-parsed upon re-evaluation)?
Use the save and load commands to store arbitrary data. This is in the Sage notebook:
sage: v = [1..10]
sage: save(v,DATA+'v')
<<QUIT and RESTART your worksheet>>
sage: load(DATA+'v')
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
And what about saving some lists from the public Sage server locally and upload it back somehow after some time? For example, if I have made some operations and got a very long list as a result, how can I get that list to my local PC given that I have been working on some of the public Sage servers (say, sagenb.org)? The purposes of such action may be the following in my case:
For the last task it it usually necessary to write the list into some file using a human readable format. For example, I need to write a very long list of data into a text file in the following format:
x1 y1
x2 y2
x3 y3
...
xn yn
How can I do that? Thanks.
