When you shift off a variable you pop it out of the argument . Just try and
get the first variable of the argument another way by copying to an array
first or something .
from perldoc
Shift :
Shifts the first value of the array off and returns it, shortening the array
by 1 and moving everything do
Thanks a lot for the suggestions and solution.

Wouldn't know, don't do Python.
Perl's both hash and array use ().
But anonymous hash and array use {} and [].
Hashes use {}, arrays use [], lists use ().
When you set an element of a hash, you use {} to surround its key:
$hash{$key} = $value;

I'd be tempted to use a hash of hash of hashes, storing it like this:
$hash{$city}{$station}{add1}=$address1
$hash{$city}{$station}{add2}=$address2
$hash{$city}{$station}{state}=$state
$hash{$city}{$station}{zip}=$zip
$hash{$city}{$station}{phone}=$phone
So my loop would look like this:

you might want to consider:
