vars() used to be the way to list local variables.
>From 4 May 1994, Python 1.0.2 [1]:
vars() returns a dictionary containing the local variables;
vars(m) returns a dictionary containing the variables of
module m. Note: dir(x) is now equivalent to
vars(x).keys().
>From 13 October 1995, Python 1.3 [2]:
Two new built-in functions, "globals()" and "locals()",
provide access to dictionaries containming [sic] current
global and local variables, respectively. (These
augment rather than replace "vars()", which returns the
current local variables when called without an argument,
and a module's global variables when called with an
argument of type module.)
