Variable by label

[rocco.rossi]

Is there any function which will return a variable by passing to it
the string containing the variable's name? Something like this for
instance:

foo = some_function("foo")

or perhaps it's a dictionary. I don't know, but I would really like to
find out how it can be done. I guess it is achievable.

Thank you.

There are the globals() and locals() builtins.

>>a = 42
globals()['a']

42

vars()["foo"]

but if you are doing this you are almost certainly making your life harder
than it needs to be. Usually you really just want to keep the values in a
dict.

getattr(object, attrname, default)
