Subject: Using tuples to eliminate multiple dict values

I need a dictionary that returns the same value for multiple keys.

i.e.

(1)   >>> dict = { (1,2,3) : 'text' , (5,6,7) : 'other text' }
(2)   >>>dict[1]
(3)   'text'

I cant figure out what i need on line 2 to make this scenario work. Is
there a simple way to check if the a number is present in the key and
then return the value?

Thanks

I think I must be missing something. Can you not do the following?

>>> d = { 1:'text', 2:'text', 3:'text', 5:'other text', 6:'other text', 7:'other text' }
>>> d[1]
'text'



If you are they need to share the same value you can also do something like this.

>>> t1 = [ 'text' ]
>>> t2 = [ 'other text' ]
>>> d = { 1:t1, 2:t1, 3:t1, 5:t2, 6:t2, 7:t2 }
>>> d[1]
['text']
>>> d[1][0]='new text'
>>> d[2][0]
'new text'
>>> d
{1: ['new text'], 2: ['new text'], 3: ['new text'], 5: ['other text'], 6: ['other text'], 7: ['other text']}
