chances are that you need a 'bag' for your new variables.  Your program
can't possibly know in advance the names, anyway, can it? 

try to use a dictionary:

    b = dict(read_items())

where read_items returns a list of name-value tuples. 

and iterate through 'b' like so

    for name in b:
        print name, "=", b[name]
  
If you think you need something else, try to describe
your requirements as precise as possible.
