That will create a dict with 2 keys, both of which are tuples.

If you want multiple keys, then you must provide them separately:

my_dict = {1: 'text', 2: 'text', 3: 'text', 5: 'other text', 6 : 'other 
text', 7: 'other text'}

or use 'for' to iterate through the keys for each value:

my_dict = dict([(k, 'text') for k in (1, 2, 3)] + [(k, 'other text') for 
k in (5, 6, 7)])

or something similar.
