You could do:

# WARNING: Untested code
index = -1
for i in x:
    if i > n:
        index = i
        break

This would work, and unless you can make assumption about the list, I
doubt it can be faster. If you can assume that for example the list is
sorted, it should be possible to do it faster, although I would not know
exactly how.

yours,
Gerrit.
