Example:: In [1]: l = ['hello',10,'world'] In [2]: %store l Stored 'l' (list) In [3]: exit (IPython session is closed and started again...) ville@badger:~$ ipython In [1]: l NameError: name 'l' is not defined In [2]: %store -r In [3]: l Out[3]: ['hello', 10, 'world'] Usage: * ``%store`` - Show list of all variables and their current values * ``%store spam bar`` - Store the *current* value of the variables spam and bar to disk * ``%store -d spam`` - Remove the variable and its value from storage * ``%store -z`` - Remove all variables from storage * ``%store -r`` - Refresh all variables, aliases and directory history from store (overwrite current vals) * ``%store -r spam bar`` - Refresh specified variables and aliases from store (delete current val) * ``%store foo >a.txt`` - Store value of foo to new file a.txt * ``%store foo >>a.txt`` - Append value of foo to file a.txt It should be noted that if you change the value of a variable, you need to %store it again if you want to persist the new value. Note also that the variables will need to be pickleable; most basic python types can be safely %store'd. Also aliases can be %store'd across sessions. To remove an alias from the storage, use the %unalias magic.
