The '''pymol.stored''' helper variable serves as a namespace for user defined globals which are accessible from [[iterate]]-like commands. The [[iterate]] commands by default expose the '''pymol''' module namespace as the [https://docs.python.org/2/library/functions.html#eval globals] dictionary, so '''pymol.stored''' is accessible as '''stored''', and (user defined) members as '''stored.''membername'''''.

== Example ==

Count number of atoms with a PyMOL script:

<syntaxhighlight lang="python">
stored.count = 0
iterate all, stored.count += 1
print("number of atoms:", stored.count)
</syntaxhighlight>

Count number of atoms with a Python script:

<syntaxhighlight lang="python">
from pymol import cmd
from pymol import stored
stored.count = 0
cmd.iterate("all", "stored.count += 1")
print("number of atoms:", stored.count)
</syntaxhighlight>

== Problems ==

There is no guarantee that other scripts or plugins don't use the same '''stored''' member names. It is recommended that properly written plugins use the [[Iterate#"space" argument|"space" argument]] with '''cmd.iterate''' and '''cmd.alter''' to define their own global namespace.
