Hi,
Using pastebin.com, I pasted this file:
def profit(n):
return 1.1*n
Then I clicked on "Raw" to get this URL:
http://pastebin.com/raw.php?i=Y6zkrjUp
In a worksheet I can now paste the following, the file I put at
pastebin then gets loaded as a ".sage" file (so with full Sage
preparsing):
f = get_remote_file("http://pastebin.com/raw.php?i=Y6zkrjUp";)
import shutil; shutil.move(f, f+'.sage')
load f+'.sage'
Then I can use the code that was defined in that paste. Anybody else
can do the same.
You can edit the code, but then I think it has to be a new paste,
which has a new URL.
