Why not use a dictionary for that?
This way you could add and remove values in/from your dictionary just as you wanted.
my_dict = {
   'var1': 0,
   'var2': 0,
    ...
}
You can delete by doing my_dict.pop('var1') if you need the value back or del my_dict['var1'] otherwise and add items with my_dict['var3'] = 0.
