It probably is, but is it slow enough for you notice it? You could try a list
comprehension:

b = [int(val) for val in a]

I don't know how this compares speed-wise with the map() solution already
offered, but I like list comprehensions better than map() anyway :). You could
do a benchmark if this part of your application is critical.
