Access to the list of tuples

Question

I have a list containing several tuples, for example:

[('a_key', 'a value'), ('another_key', 'another value')]

where the first values ​​of the tuple act as dictionary keys. Now I'm looking for a python-like way to access key / value pairs, for example:

"mylist.a_key" or "mylist['a_key']"

without repeating the list. any ideas?
