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

a = 1

b = eval("a")
b 1
a =1
b = globals()["a"]
b 1
a =1
b = locals()["a"]
b

1

Perfect. Thank you all for your replies.
