That, given an array a of n integers, returns the smallest positive integer (greater than 0) that does not occur in a. python

Testing for the presence of a number in a set is fast in Python so you 
could try something like this:

def minpositive(a):
    A = set(a)
    ans = 1
    while ans in A:
       ans += 1
    return ans
