Can I use a sublist as an argument in python?

[MartinBerlin]

I have a nested list:

city = [['house', 'street', 'park'], ['car', 'bike', 'train']]

Now I want to define a function what takes the first sublist of city as the input (argument) with the variable 'part', what takes the value 0 or 1 (depending on if I want to use the first or the second sublist:

def sublist(city[part]):

The editor returns the error:

def sublist(city[part]):
                ^
SyntaxError: invalid syntax 

Is it possible to use a sublist as an argument in python? If yes, how can I do it?
