Questions about tuple?

[Mindy]

Hey, given a tuple t(a,b), is there any function in
Python that I can get a, b individually from t?
Actually, I have a list whose element is tuples. Say:

tuple_list = [(1,'a'),(3,'b'),(2,'l'),(8,'p')]

Then I want to get two lists from this tuple_list. The
first list contains the first elements in the tuple of
the tuple_list. 

first_list = [1,3,2,8]

And the second list contains all the second elements,
also maintaining the original order as in tuple_list.

second_list = ['a','b','l','p']

So how to get this easily? Thanks!
