I know I can write a function to do this, but is there anything built-in?
I'd say that we have established that there is no shortcut, no built-
in for this. You write you own function:
string_to_int = lambda s: int(float(s))
Then you apply it to your list of strings:
list_of_integers = map(string_to_int, list_of_strings)
Of course, this will be horribly slow if you have thousands of
strings. In such a case you should use an iterator (assuming you use
python 2.7):
import itertools as it
iterator = it.imap(string_to_int, list_of_strings)
Regards,

if the goal is speed, then you should use generator expressions:
list_of_integers = (int(float(s)) for s in list_of_strings)
