>>> list('abcdef')
['a', 'b', 'c', 'd', 'e', 'f']
>>> tuple('abcdef')
('a', 'b', 'c', 'd', 'e', 'f')
>>> 

Tuples are very similar to lists and support slicing, indexing, and concatenation. The difference is that you cannot modify the contents of a tuple. Therefore tuples can be used as dictionary keys.

>>> {(1,2,3): 123}
{(1, 2, 3): 123}
>>> {[1,2,3]: 123}
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
TypeError: list objects are unhashable
>>>
