store(self, parameter_s='')
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.
Lightweight persistence for python variables.
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
