returning the 2nd value of a sublist.

[v13tn1g]

lets say L=[ [asdf,4.0], [fdsa,8], [abcd,98]

how can i get the 2nd value of the sublist returned. for example if it were a function

return_value(as df, L)------------> it would return 4.0

how can i do this? any help would be appreciated.

Why not use a dictionary instead? That is exactly what you are trying to do.

>>> D = dict([ ["asdf",4.0], ["fdsa",8], ["abcd",98]])
>>> D
{'abcd': 98, 'fdsa': 8, 'asdf': 4.0}
>>> D["asdf"]
4.0
>>>

i dont think i can use dictionaries yet because our class is not there yet, i think i have to base my answers using methods of lists.

thanks for the reply though

Try to make a for loop that looks at each of the sub-lists, and if the first element of the sub-list is equal to the given key, return the second element.
I hope this is helpful.

>>> l=[["asdf",4.0],["fdsa",8],["abcd",98]]
>>> def return_value(key,list_):
...   for entity in list_:
...     if entity[0] == key:
...       return entity[1]
... 
>>> return_value('asdf',l)
4.0
